Description

1,3,4,6-Tetra-o-Galloylglucose is a naturally occurring polyphenolic compound belonging to the hydrolyzable tannin class, specifically a gallotannin. This high-purity chemical is valued for its potent antioxidant and biological activities, making it a critical reference standard and active ingredient in advanced research and development. It is primarily sought by the pharmaceutical, nutraceutical, and cosmetic industries for applications in formulation development, efficacy studies, and quality control.

Application

• Pharmaceutical Research: Serves as a key reference standard and active pharmaceutical ingredient (API) intermediate for studying antioxidant, anti-inflammatory, and potential anti-cancer mechanisms.
• Nutraceutical Formulation: Used as a bioactive component in dietary supplements targeting oxidative stress and metabolic health due to its high antioxidant capacity.
• Cosmetic & Skincare: Incorporated into anti-aging and protective formulations for its ability to neutralize free radicals and protect skin from environmental damage.
• Biochemical Research: Employed as a specific enzyme inhibitor (e.g., for α-glucosidase) in metabolic pathway studies and drug discovery programs.
• Analytical Standard: Essential for the qualitative and quantitative analysis (e.g., via HPLC, LC-MS) of tannin-rich plant extracts in quality control laboratories.
• Functional Food & Beverage: Potential application as a natural preservative and functional additive to enhance the health profile of food products.
