Description

Benzoic acid, 3,4,5-trihydroxy-, (2R,3R)-2-[(1R)-6'-[(2R,3R)-3,4-dihydro-3,5,7-trihydroxy-2H-1-benzopyran-2-yl]-2',3',4,4',5,6-hexahydroxy[1,1'-biphenyl]-2-yl]-3,4-dihydro-5,7-dihydroxy-2H-1-benzopyran-3-yl ester is a complex polyphenolic ester belonging to the tannin family, specifically a hydrolyzable tannin derivative. This compound is valued for its potent antioxidant and metal-chelating properties, which are central to its biological and industrial utility. It serves as a critical high-purity reference standard and active ingredient for research and development in the pharmaceutical, nutraceutical, and cosmetic industries.

Application

• Pharmaceutical Reference Standard: Used as a certified reference material (CRM) for analytical method development, validation, and quality control in drug discovery and natural product research.
• Nutraceutical Ingredient: Incorporated into dietary supplements for its potential antioxidant and health-promoting benefits, leveraging its natural polyphenolic structure.
• Cosmetic Actives: Formulated into anti-aging and skin-protective creams and serums due to its ability to scavenge free radicals and protect against oxidative stress.
• Biochemical Research: Employed in in vitro and in vivo studies to investigate mechanisms of action related to inflammation, enzyme inhibition, and cellular signaling pathways.
• Analytical Chemistry: Serves as a key marker compound for the identification and quantification of tannins and related polyphenols in complex botanical extracts using HPLC, LC-MS, and other chromatographic techniques.
