Schisandrol A 98% Supplier: CAS 7432-28-2, HPLC Verification & Bulk Buying Guide Quick Answer Schisandrol A (also known as Schisandrin or Schizandrin, CAS 7432-28-2) is the principal dibenzocyclooctadiene lignan of Schisandra chinensis fruit. When sourcing Schisandrol A 98%, the single most important verification point is whether the supplier's HPLC method actually separates Schisandrol A from its closely related isomers (Schisandrol B, Schisandrin B and C, gomisin-type lignans) — a generic purity number alone cannot tell you this. Request the batch chromatogram, confirm the main peak identity, and check storage and packaging details before scaling to commercial quantities. Key Takeaways · Schisandrol A = Schisandrin (Schizandrin): one compound, several names — confirm which one your specification means before comparing quotations. · Schisandra lignans form a family of structurally similar isomers; HPLC methods must resolve them, and "98%" without a chromatogram proves nothing. · ≥98% HPLC is the common high-purity grade for ingredient development and research use. · The compound is sensitive to light and moisture over time; cool, dry, light-protected storage protects batch consistency. · For US-bound supply, confirm the intended use and regulatory pathway with your own regulatory team — documentation requirements depend on the application. 1. Chemical Identity and Specifications Item Specification Product Name Schisandrol A (Schisandrin; Schizandrin) CAS Number 7432-28-2 Molecular Formula C₂₄H₃₂O₇ Molecular Weight 448.51 g/mol Compound Class Dibenzocyclooctadiene lignan Botanical Source Fruit of Schisandra chinensis (Chinese magnolia vine) Appearance White to off-white crystalline powder Purity ≥98% (HPLC) Solubility Soluble in methanol, ethanol, DMSO; low solubility in water Documentation COA, HPLC, MS/NMR, SDS, TDS per batch Naming note: suppliers and literature use Schisandrol A, Schisandrin and Schizandrin interchangeably for CAS 7432-28-2. Some catalogs list "Schisandrol B" as a separate compound (a different, more saturated lignan). Because the names look similar, always match quotations by CAS number, not by name alone. 2. Schisandrol A 98% vs. Standardized Schisandra Extract Parameter Schisandrol A 98% (purified) Schisandra extract (standardized) Composition Single lignan compound Complex extract with multiple Schisandra lignans Purity basis ≥98% Schisandrol A by HPLC Total lignans or Schisandrol A content standardized Typical use Ingredient development, analytical reference, research Formulations where a defined extract is acceptable Analytical identity Single dominant peak with resolved isomer region Multi-peak lignan fingerprint Price logic Purity- and process-driven Raw-material- and ratio-driven Both product types are legitimate — the procurement risk is buying one while believing you ordered the other. Put the CAS number and the purity basis in your specification sheet before requesting quotations. 3. HPLC Verification: The Isomer Question This is where Schisandrol A sourcing differs from most botanical single compounds. Schisandra chinensis contains a family of closely related dibenzocyclooctadiene lignans — Schisandrol A, Schisandrol B, Schisandrin B, Schisandrin C, gomisin A, gomisin N and others — several of which elute close together on typical reversed-phase methods. When auditing a Schisandrol A 98% batch file: 1. Ask for the full chromatogram, not the purity figure. Check that the isomer region is resolved and that minor lignan peaks are reported. 1. Confirm main-peak identity. MS or NMR data should support that the dominant peak is Schisandrol A (CAS 7432-28-2), not a co-eluting isomer such as Schisandrol B. 1. Method transparency. Column type, mobile phase, wavelength and integration parameters should be stated, so your own lab can reproduce the result. 1. Impurity and residue data. Residual solvents and heavy metals should match the requirements applicable to your market and intended use. 1. Batch traceability. The COA batch number must match the drum labels of the shipment you receive. A practical sequence used by many procurement teams: order a 20 g sample with full documentation, run independent HPLC (ideally with an isomer-resolution check) at a third-party laboratory, then scale. CQ HERB supports this sample-first model with batch-specific documentation. 4. Stability, Packaging and Storage · Light and moisture: lignans gradually degrade under light exposure and humid conditions; containers should be sealed and light-protected. · Storage: cool and dry, protected from light; follow the SDS/TDS for the specific grade. Research-grade solutions in DMSO are typically stored frozen in aliquots. · Shelf life: typically 24 months under recommended conditions; check the retest date on the COA. · Formulation note: low water solubility — ethanol, glycol or DMSO-based premixes are common in development work. Confirm compatibility with your system early. · Shipping: standard sealed export packaging; for humid climates, confirm desiccant and moisture-barrier arrangements with your supplier. 5. Intended Applications and Regulatory Context Schisandrol A 98% is supplied for: · Ingredient development and research — as a reference compound and botanical-derived active for phytochemistry, analytical method development and natural-product research. · Formulation development — as a raw material for product development teams working with Schisandra-derived ingredients. Regulatory note: Schisandra chinensis extracts are familiar to North American and European buyers, but permitted use, labeling and claim language differ by market and application. Confirm the intended use and applicable framework with your regulatory team. CQ HERB supplies the ingredient with technical documentation — it is not a finished product and carries no product claims. 6.

Ruscogenin 98% Supplier: CAS 472-11-7, HPLC Purity & Bulk Sourcing Guide Quick Answer Ruscogenin (CAS 472-11-7) is a steroidal sapogenin obtained primarily from Ruscus aculeatus (butcher's broom) root. When sourcing Ruscogenin 98%, verify four things before ordering: a batch-specific HPLC chromatogram, the botanical source statement, identity confirmation data (MS/NMR or IR), and storage-relevant documentation. Because the material is a purified single compound with a defined melting range, identity and purity can be checked analytically — which is why buyers should insist on real batch data rather than a template COA. Key Takeaways · Ruscogenin is a steroidal sapogenin (C₂₇H₄₂O₄, MW 430.63), not a standardized plant extract — the two are different products with different price logic. · ≥98% HPLC is the common high-purity specification used in ingredient development and research applications. · Request batch COA + actual HPLC chromatogram + MS/NMR data; confirm the batch number on the documents matches your shipment. · Storage at 2–8 °C, light-protected, matters: ruscogenin is sensitive to prolonged air and light exposure. · Solubility in water is low; formulations typically rely on ethanol- or glycol-based systems — confirm the grade and presentation with your supplier early. · Documentation expectations differ by market; for US-bound cosmetic or research supply, confirm the intended use with your regulatory team. 1. Chemical Identity and Specifications Item Specification Product Name Ruscogenin (Ruscogenine) CAS Number 472-11-7 Molecular Formula C₂₇H₄₂O₄ Molecular Weight 430.63 g/mol Botanical Source Ruscus aculeatus L. root (butcher's broom) Appearance White to off-white crystalline powder Purity ≥98% (HPLC) Melting Point 182–186 °C Solubility Soluble in DMSO, ethanol; low solubility in water Storage 2–8 °C, protected from light and moisture Documentation COA, HPLC, MS/NMR, SDS, TDS per batch Ruscogenin belongs to the spirostane-type steroidal sapogenins. Its defined melting range and single-compound nature make it practical to verify identity by melting point determination, IR, or MS, in addition to HPLC purity — a useful cross-check when evaluating a new supplier. 2. Ruscogenin 98% vs. Standardized Butcher's Broom Extract Buyers frequently compare quotations for products that are not equivalent: Parameter Ruscogenin 98% (purified) Butcher's broom extract (standardized) Composition Single steroidal sapogenin Complex extract containing ruscogenin plus other saponins Purity basis ≥98% Ruscogenin by HPLC Ruscogenin content standardized to a stated level Typical use Ingredient development, analytical reference, research Formulations where a defined extract is acceptable Price logic Purity- and process-driven Raw-material- and ratio-driven Analytical identity Sharp single HPLC peak Multi-peak botanical fingerprint If your specification calls for "98% ruscogenin", a 10%–30% standardized extract will not satisfy it, regardless of the price difference. Confirm the analytical basis in writing before comparing costs. 3. HPLC and COA Verification: What to Check A credible Ruscogenin 98% batch file should include: 1. Batch-specific HPLC chromatogram — with column type, mobile phase, detection wavelength, and integration parameters, not just a percentage. 1. Identity confirmation — MS and/or NMR data supporting the spirostane structure; melting point within 182–186 °C is a quick secondary check. 1. Impurity profile — related sapogenins and process-related impurities, reported or stated as within specification. 1. Residual solvents and heavy metals — results should match the requirement set applicable to your market and intended use. 1. SDS and TDS — consistent with the COA and current for the grade supplied. 1. Batch traceability — the batch number on the COA must match the labels on the drums you receive. A practical procurement sequence: request a 20 g sample with the full documentation package, run independent HPLC verification at a third-party laboratory, then scale to commercial quantities. CQ HERB supports this sample-first evaluation model with batch-specific documentation. 4. Solubility, Formulation Handling and Stability Ruscogenin is poorly water-soluble, which shapes how formulators work with it: · Solvent systems: ethanol, glycol, or DMSO-based premixes are common in development work; confirm compatibility with your final system early. · Thermal exposure: keep processing temperatures well below the melting range and avoid prolonged heat during incorporation. · Light and air: the material should be handled in closed containers, protected from light; long exposure to air reduces content over time. · Storage: 2–8 °C, dry, light-protected. Shelf life is typically stated as 36 months under recommended conditions; check the retest date on the COA. · Shipping: for warm-climate destinations, confirm insulated packaging and transit documentation with your supplier — heat exposure during transit is a common, avoidable quality issue. 5. Intended Applications and Regulatory Context Ruscogenin 98% is supplied for: · Cosmetic raw-material development — used by formulators as a botanical-derived active ingredient in skin and body care development; finished-product claims are the responsibility of the brand and must comply with the applicable cosmetic regulation in the destination market. · Research and analytical applications — as a reference compound for phytochemical, chromatographic, and natural-product research. Regulatory note: permitted use, labeling, and claim language for ruscogenin-containing products differ by market. US-bound supply may fall under cosmetic ingredient or research-material frameworks depending on intended use and how the material is presented; buyers should confirm the applicable pathway with their regulatory team. CQ HERB supplies the ingredient with technical documentation — it is not a finished product and carries no product claims. 6.

Glabridin (CAS 59870-68-7) is a prenylated isoflavan purified from the root of Glycyrrhiza glabra (licorice). When sourcing Glabridin 98%, buyers should verify three things before placing an order: batch-specific HPLC chromatograms (not just a COA summary), botanical origin and extraction process documentation, and heavy-metal and residual-solvent data consistent with the destination market's cosmetic or research-use regulations. Reputable suppliers provide 20 g-scale samples with complete documentation before commercial quantities. Key Takeaways · Glabridin is the key purified isoflavan in licorice root; commercial grades range from standardized licorice extracts (10%–40%) to high-purity ≥98% HPLC material. · "98% Glabridin" and "licorice extract standardized to 40% glabridin" are different products with different price structures — confirm which one you are comparing. · Always request: batch COA, HPLC chromatogram, SDS, heavy metals, residual solvents, and botanical source statement. · Glabridin is light- and oxidation-sensitive; packaging and storage conditions directly affect batch-to-batch consistency. · Regulatory status differs by market and application — confirm the intended use (cosmetic ingredient, research compound) with your regulatory team before purchase. 1. Chemical Identity and Specifications Item Specification Product Name Glabridin CAS Number 59870-68-7 Molecular Formula C₂₀H₂₀O₄ Molecular Weight 324.37 g/mol Botanical Source Root of Glycyrrhiza glabra L. Appearance White to off-white crystalline powder Purity ≥98% (HPLC) Solubility Soluble in ethanol, DMSO; poorly soluble in water Documentation COA, HPLC, SDS, TDS available per batch Because Glabridin is a single purified compound rather than a standardized extract, buyers can verify identity and purity analytically with standard laboratory methods, which is one reason it is widely used in cosmetic raw-material and natural-product research programs. 2. Glabridin 98% vs. Standardized Licorice Extract: Know What You Are Comparing A frequent source of confusion in licorice-derived quotations is the difference between purified Glabridin and standardized licorice extract: Parameter Glabridin 98% (purified compound) Licorice extract (standardized, e.g. 40% Glabridin) Composition Single isoflavan compound Complex extract with multiple licorice constituents Purity basis ≥98% Glabridin by HPLC Glabridin content standardized, balance is other extractives Typical use Cosmetic actives, analytical reference, research Finished-product formulations, cost-driven applications Price basis Per-kilogram, purity-driven Lower unit cost, higher inclusion rates Analytical identity Sharp single HPLC peak Multiple-peak fingerprint Before comparing quotations, confirm the basis: "98% Glabridin" and "40% Glabridin licorice extract" are not interchangeable, and neither price nor formulation math can be compared directly. 3. HPLC Verification: What a Valid COA Should Contain When auditing a supplier's Certificate of Analysis for Glabridin 98%, check for the following: 1. Batch-specific data. The COA must reference the exact batch number you will receive. Template COAs without batch numbers are a warning sign. 2. HPLC method and chromatogram. Ask for the actual chromatogram, not only the purity figure. The report should state the column type, detection wavelength, and integration method. 3. Identity confirmation. For high-value shipments, IR or MS confirmation of structure adds assurance that the compound is Glabridin rather than a co-eluting peak. 4. Impurity profile. Residual licorice congeners (e.g., glabrene, liquiritigenin) and process-related impurities should be reported or stated as within specification. 5. Heavy metals and residual solvents. Results should align with the requirements of your destination market — for example, the technical documentation expectations for cosmetic raw materials in the EU or North America. 6. SDS and TDS. Safety data and technical data sheets should be current and consistent with the COA. A practical approach used by many procurement teams: request a 20 g sample with full documentation, run independent HPLC verification at a third-party laboratory, then move to commercial quantities. CQ HERB supports sample evaluation with batch-specific documentation for this purpose. 4. Stability, Packaging and Storage Glabridin is sensitive to light and oxidation. In practice, this affects bulk handling: · Packaging: double-layer PE bags inside fiber drums for 1–25 kg quantities; sealed foil bags for smaller development batches. · Storage: cool, dry, light-protected conditions; keep containers tightly closed. · Shelf life: typically 24 months when stored as recommended; retest dates should appear on the COA. · Formulation note: because solubility in water is low, formulators commonly work with ethanol-based or solubilized systems; discuss the intended formulation format with your supplier so the recommended grade and particle presentation match. 5. Intended Applications and Regulatory Context Glabridin 98% is supplied for: · Cosmetic raw-material development — as a botanical-derived active ingredient used by formulators in skin-care product development, where the finished product's claims must comply with local cosmetic regulations. · Research applications — as a reference compound and research material in phytochemistry and natural-product studies. Regulatory note: the permitted use, labeling, and claim language for Glabridin-containing products differ by market (cosmetic ingredient frameworks, ingredient nomenclature such as INCI, and local advertising rules). Buyers should confirm the intended use and destination-market requirements with their own regulatory team. CQ HERB supplies the ingredient together with technical documentation; the ingredient itself is not a finished product and carries no product claims. 6. Supplier Evaluation Checklist Use this checklist when comparing Glabridin suppliers: · Batch-specific HPLC chromatogram provided (not just a purity number) · Botanical origin and extraction process described transparently · Heavy metals and residual solvents reported · SDS, TDS, and COA consistent with each other · Sample policy: small-quantity samples available for third-party verification · Traceable production information and stable multi-batch supply · Export documentation experience for your destination market · Responsive technical support (not only sales support) Nanjing Spring & Autumn Biological Engineering Co., Ltd.

Dimethylcurcumin (ASC-J9) CAS 52328-98-0: Chemical Properties, Androgen Receptor Research, Applications & Buying Guide A Research-Oriented Guide to a Curcumin Analogue and Androgen Receptor Degradation Enhancer CAS No. 52328-98-0 | Molecular Formula C23H24O6 | Molecular Weight 396.43 g/mol     Quick Answer Dimethylcurcumin, commonly known as ASC-J9 or GO-Y025, is a synthetic curcumin analogue that has been extensively investigated in laboratory and preclinical research related to androgen receptor (AR) signaling. Its chemical identity is associated with CAS No. 52328-98-0, molecular formula C23H24O6, and molecular weight 396.43 g/mol. Unlike conventional androgen receptor antagonists that primarily interfere with androgen binding or receptor signaling, ASC-J9 has been investigated as an androgen receptor degradation enhancer. Research has examined its ability to promote degradation of androgen receptor proteins and thereby alter AR-dependent signaling in experimental models. Published studies have investigated ASC-J9 in a range of experimental systems, including prostate cancer models, androgen receptor-associated disorders, bladder cancer models, and spinal and bulbar muscular atrophy research. These studies include in vitro cellular experiments and in vivo animal models; such findings should not be interpreted as evidence of established clinical efficacy in humans. For researchers and organizations sourcing Dimethylcurcumin, important purchasing considerations include chemical identity, purity, analytical characterization, batch consistency, storage conditions, and supporting technical documentation.     Key Takeaways · Dimethylcurcumin is also known as ASC-J9 and GO-Y025. · CAS Number: 52328-98-0. · Molecular Formula: C23H24O6. · Molecular Weight: 396.43 g/mol. · It is a synthetic curcumin analogue, rather than native curcumin itself. · ASC-J9 has been investigated as an androgen receptor degradation enhancer. · Published research has examined its effects on AR protein degradation and AR-related signaling. · Research has included prostate cancer, bladder cancer, spinal and bulbar muscular atrophy, and other AR-associated experimental models. · Research-grade ASC-J9 is commonly supplied as a solid/powder and may require low-temperature storage depending on the supplier's specification. · Analytical verification is important when purchasing high-purity Dimethylcurcumin for research. · ASC-J9 should be presented on a research-oriented website as a research compound, not as an approved therapeutic product.     1. What Is Dimethylcurcumin (ASC-J9)? Dimethylcurcumin is a synthetic compound structurally related to curcumin and is widely known in the scientific literature as ASC-J9. The compound is identified chemically as: (1E,4Z,6E)-1,7-bis(3,4-dimethoxyphenyl)-5-hydroxyhepta-1,4,6-trien-3-one Public chemical databases list Dimethylcurcumin, ASC-J9, and GO-Y025 among its synonyms. PubChem identifies CAS No. 52328-98-0 and molecular formula C23H24O6, with a molecular weight of approximately 396.4 g/mol. Commercial research suppliers also identify ASC-J9 using the same CAS number and molecular formula and commonly describe high-purity material as a research-grade powder. Although its name contains "curcumin," Dimethylcurcumin should not be treated as simply another commercial grade of curcumin. It is a distinct synthetic curcumin analogue with its own molecular structure and research profile. This distinction is particularly important for purchasing, analytical testing, literature searches, and regulatory documentation.     2. Dimethylcurcumin vs. Curcumin The relationship between Dimethylcurcumin and curcumin is an important point for researchers. Curcumin is a naturally occurring diarylheptanoid associated with Curcuma longa. Dimethylcurcumin, by contrast, is a chemically modified analogue that contains methoxy-substituted aromatic groups and has a different molecular formula and molecular weight. Property Dimethylcurcumin / ASC-J9 Curcumin Common Name Dimethylcurcumin Curcumin CAS 52328-98-0 458-37-7 Formula C23H24O6 C21H20O6 Molecular Weight 396.43 g/mol 368.38 g/mol Relationship Synthetic curcumin analogue Naturally occurring curcuminoid Research Focus AR degradation and AR-related signaling Broad pharmacological and biochemical research Research Status Experimental/research compound Widely studied natural compound The two compounds therefore should not be substituted for one another simply because they belong to the broader curcumin-analogue research area.     3. Chemical Identification of ASC-J9 Accurate chemical identification is particularly important for research compounds because different suppliers may use overlapping synonyms. Core Chemical Information Property Information Product Name Dimethylcurcumin Common Research Name ASC-J9 Alternative Name GO-Y025 CAS Number 52328-98-0 Molecular Formula C23H24O6 Molecular Weight 396.43 g/mol Chemical Class Curcumin analogue IUPAC Name (1E,4Z,6E)-1,7-bis(3,4-dimethoxyphenyl)-5-hydroxyhepta-1,4,6-trien-3-one Physical Form Solid / powder Research Target Androgen receptor-related research The identity and molecular information above are supported by PubChem and commercial analytical product records.     4. Why Is ASC-J9 Important in Research? The scientific interest surrounding ASC-J9 largely comes from its unusual relationship with the androgen receptor. The androgen receptor (AR) is a nuclear receptor that regulates gene transcription in response to androgen hormones. AR signaling has important physiological roles and has also been extensively investigated in diseases and biological conditions in which androgen signaling is altered. ASC-J9 attracted research attention because studies indicated that it could promote AR protein degradation, rather than simply competing with androgens for receptor binding. This creates an important conceptual distinction: ASC-J9 research focuses on changing the abundance and activity of AR protein, while conventional antiandrogen research often focuses on blocking receptor activation. Early research demonstrated that ASC-J9 could disrupt interactions between AR and selected coregulators and increase AR degradation in experimental systems. Subsequent studies expanded this research into additional AR-associated models.     5. How Does ASC-J9 Work in Experimental Research? AR Degradation as a Research Mechanism One of the defining characteristics of ASC-J9 is its reported ability to enhance degradation of androgen receptor protein. Research has suggested that ASC-J9 can interfere with interactions between AR and selected coregulators, leading to increased AR degradation. Experimental work has also linked ASC-J9-mediated AR degradation to proteasome-dependent processes. This mechanism is different from simply reducing androgen production. The conceptual pathway can be simplified as: ASC-J9 ↓ Alteration of AR–coregulator interactions ↓ Enhanced AR degradation ↓ Reduced AR protein abundance ↓ Changes in AR-dependent transcription ↓ Changes in downstream cellular responses This model has been investigated primarily through laboratory and animal studies.     6. What Does the Scientific Literature Show? Research on ASC-J9 spans more than a decade. An early study published in Nature Medicine investigated ASC-J9 in a model of spinal and bulbar muscular atrophy. The study reported that ASC-J9 disrupted interactions between androgen receptor and coregulators and increased degradation of the mutant androgen receptor in experimental systems. The researchers also investigated the compound in transgenic mice. Later research examined ASC-J9 in prostate cancer models. Studies reported degradation of both full-length AR and an AR splice variant in experimental prostate cancer cell models, accompanied by reduced AR transcriptional activity and cell growth. Additional preclinical studies investigated ASC-J9 in combination with other experimental approaches, including radiation and chemotherapy models. For example, research published in Cancer Letters examined the combination of ASC-J9 with docetaxel in castration-resistant prostate cancer models. A review published in 2021 summarized research involving ASC-J9 across multiple AR-associated disease models, including prostate cancer, benign prostatic hyperplasia, bladder cancer, liver disease, spinal and bulbar muscular atrophy, ovarian cancer, and melanoma. Important Scientific Qualification These publications demonstrate research interest and preclinical findings, not established clinical efficacy. Therefore, CQHERB's website should describe ASC-J9 in terms such as: · Research compound · Research chemical · Curcumin analogue · AR degradation research · Experimental compound · Preclinical research and should avoid presenting ASC-J9 as an approved medicine or making direct therapeutic claims.     7. Research Applications of Dimethylcurcumin ASC-J9 has been investigated in several research areas. 7.1 Androgen Receptor Research This is the most characteristic research application. Researchers use ASC-J9 to investigate: · AR protein degradation · AR signaling · AR transcriptional activity · AR–coregulator interactions · AR-dependent cellular pathways     7.2 Prostate Cancer Research ASC-J9 has been investigated in multiple prostate cancer cell and animal models, including models of castration-resistant prostate cancer. Studies have examined whether AR degradation can alter tumor-cell proliferation and AR-dependent signaling. These findings remain within the context of experimental research and should not be presented as evidence that ASC-J9 is an approved cancer treatment.     7.3 Spinal and Bulbar Muscular Atrophy Research ASC-J9 has also been studied in models of spinal and bulbar muscular atrophy, a condition associated with mutant androgen receptor aggregation. The original study reported that ASC-J9 reduced mutant AR aggregation and improved disease-related phenotypes in experimental mice.     7.4 Bladder Cancer Research Research has also investigated ASC-J9 in bladder cancer models, particularly in relation to AR and NF-κB signaling and chemotherapy response.     8. Analytical Considerations for ASC-J9 For research-grade Dimethylcurcumin, chemical identity and purity should be verified through appropriate analytical methods. Commonly relevant analytical techniques include: HPLC HPLC can be used to evaluate chromatographic purity and batch consistency. LC-MS / MS Mass spectrometry can support molecular identity confirmation and quantitative analysis. A published analytical method specifically developed LC-MS/MS determination of ASC-J9 in mouse serum and tissues. NMR NMR can provide structural characterization and is particularly useful when confirming the identity of research compounds. COA A Certificate of Analysis should identify the product, batch, assay/purity, analytical method, and relevant quality parameters. For high-value research compounds, buyers should ideally review analytical documentation before placing larger orders.     CQHERB Technical Insight For Dimethylcurcumin and other research-oriented botanical or bioactive compounds, identity and analytical traceability should be considered alongside purity. A reliable research-material supplier should be able to clearly distinguish: Product identity → analytical method → purity → batch information → storage → documentation This is especially important for ASC-J9 because the compound is known under several names, including Dimethylcurcumin, ASC-J9 and GO-Y025. Using the CAS number 52328-98-0 together with the molecular formula and analytical documentation can help minimize purchasing and identification errors.     9. Storage and Handling Publicly available research-product specifications commonly recommend storing ASC-J9 at low temperature, with −20°C being specified by several commercial research suppliers. For commercial research material, customers should follow the supplier-specific COA, SDS and storage instructions rather than relying on a generic recommendation. Recommended purchasing documentation should include: · Product specification · COA · SDS/MSDS · Storage conditions · Batch number · Retest or expiry information where applicable · Analytical data upon request     10. Who Uses Dimethylcurcumin? ASC-J9 is primarily relevant to organizations conducting laboratory and preclinical research. Potential users include: · University research laboratories · Pharmaceutical research organizations · Biotechnology companies · Molecular biology laboratories · Cancer biology research groups · Androgen receptor research laboratories · Drug discovery teams · Academic research institutions The appropriate use and regulatory status depend on the customer's jurisdiction, research protocol, and intended application.     11. Buyer Guide: How to Evaluate an ASC-J9 Supplier When sourcing Dimethylcurcumin, buyers should not evaluate suppliers based solely on the advertised purity number. A more complete evaluation should include: 1. Correct Chemical Identity Confirm: CAS 52328-98-0 and cross-check the molecular formula and analytical data. 2. Purity Method Ask whether the stated purity is determined by HPLC or another analytical method. 3. Batch Documentation Request a current COA corresponding to the actual batch. 4. Structural Confirmation For research-grade material, MS and/or NMR data can provide additional confidence in chemical identity. 5. Storage Confirm storage temperature and packaging conditions. 6. Supply Consistency For repeated research programs, batch-to-batch consistency can be more important than obtaining the lowest initial quotation.     12. Why Research Buyers Should Distinguish ASC-J9 From Curcumin One common purchasing error is assuming that Dimethylcurcumin can be substituted with curcumin simply because ASC-J9 is a curcumin analogue. This is incorrect. The two compounds have different molecular formulas, molecular weights, structures, and research profiles. Therefore, research protocols specifying: ASC-J9 / Dimethylcurcumin / CAS 52328-98-0 should not automatically be replaced with curcumin or another curcuminoid. For reproducible experimental research, the exact compound specified in the protocol should be sourced and analytically verified.     13. Frequently Asked Questions What is ASC-J9?

Why Is Bakuchiol Receiving Global Attention? The global skincare market has undergone a significant transformation over the past decade. Consumers are no longer satisfied with products that simply promise visible results—they increasingly seek ingredients that combine proven efficacy, excellent skin compatibility, and naturally derived origins. Retinol has long been regarded as the gold standard for anti-aging skincare. However, many consumers experience undesirable side effects such as dryness, redness, peeling, and increased photosensitivity, particularly those with sensitive or compromised skin barriers. These limitations have encouraged cosmetic researchers and formulators to search for botanical alternatives capable of delivering comparable cosmetic benefits with improved tolerability. Bakuchiol has emerged as one of the most promising answers to this demand. Although its chemical structure differs completely from vitamin A derivatives, numerous scientific investigations have shown that Bakuchiol can influence several biological pathways associated with skin renewal, collagen metabolism, and wrinkle reduction. This unique combination of efficacy and skin friendliness has positioned Bakuchiol as a preferred ingredient for modern anti-aging formulations. At the same time, the rapid growth of clean beauty, vegan cosmetics, and naturally derived skincare products has further accelerated the commercial adoption of Bakuchiol across North America, Europe, Japan, South Korea, and other major cosmetic markets. What Is Bakuchiol? Bakuchiol is a naturally occurring meroterpene phenol isolated primarily from the seeds and leaves of Psoralea corylifolia, a medicinal plant traditionally used in Asian herbal medicine for centuries. While the plant has a long history in traditional healthcare, Bakuchiol itself has gained widespread recognition only in recent years as scientific research has revealed its remarkable cosmetic potential. Unlike retinol, which belongs to the vitamin A family, Bakuchiol possesses an entirely different molecular structure. Nevertheless, modern biological studies suggest that it can regulate the expression of several genes involved in skin repair, extracellular matrix remodeling, and collagen production. This explains why many formulators describe Bakuchiol as a "natural retinol alternative," even though it is not chemically related to retinoids. Its excellent compatibility with sensitive skin, combined with antioxidant activity and broad formulation flexibility, has made Bakuchiol one of the most valuable plant-derived active ingredients in premium cosmetic formulations. Today, Bakuchiol is commonly found in: Anti-aging facial serums Firming creams Eye creams Moisturizers Facial oils Overnight repair treatments Premium clean beauty products Sensitive skin formulations Its versatility allows formulators to create effective skincare products for consumers seeking visible anti-aging benefits while avoiding many of the limitations associated with traditional retinoids.
