Description

Taxifolin 3'-o-Glucoside is a specific glycosylated derivative of the flavonoid taxifolin (dihydroquercetin). This compound is valued for its enhanced bioavailability and potent antioxidant properties compared to its aglycone form. It is primarily sought by manufacturers in the nutraceutical, pharmaceutical, and cosmetic industries for advanced research and product development. Our high-purity grade ensures reliable performance and consistency for your critical applications.

Application

• Nutraceutical Formulations: Used as a key bioactive ingredient in dietary supplements targeting oxidative stress and inflammation.
• Pharmaceutical Intermediates: Serves as a reference standard or a starting material for the synthesis of more complex therapeutic agents.
• Cosmetic Actives: Incorporated into anti-aging and skin-protective creams and serums for its antioxidant and potential UV-protective effects.
• Biochemical Research: Employed in in vitro and in vivo studies to investigate flavonoid metabolism, bioavailability, and biological activity.
• Functional Food & Beverages: Added to health-promoting foods and drinks to enhance their nutritional profile.
• Standard for Analytical Testing: Used as a high-purity certified reference material (CRM) for quality control and assay development in analytical laboratories.

Quality Control

Every batch of our Taxifolin 3'-o-Glucoside is produced and tested under strict quality management systems. We provide comprehensive analytical documentation, including HPLC chromatograms and full spectral data (UV, MS, NMR) for identity confirmation. A Certificate of Analysis (COA) detailing purity, related substances, and residual solvents is supplied with each shipment, ensuring traceability and compliance with your quality requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, it is recommended to store the product under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation and to minimize degradation.
