Description

3-o-Galloyl-2-o-[2-[[(5,10-Dihydro-3,7,8-Trihydroxy-5,10-Dioxo[1]Benzopyrano[5,4,3-Cde][1]Benzopyran)-2-Yl]Oxy]Galloyl]-D-Glucopyranose is a complex polyphenolic compound belonging to the hydrolyzable tannin class, specifically a C-glycosidic ellagitannin. This compound matters for its significant biological activity, serving as a key intermediate or reference standard in the study of natural product chemistry and pharmacology. It is primarily needed by research institutions, pharmaceutical developers, and nutraceutical companies focused on antioxidant, anti-inflammatory, and chemopreventive agent discovery.

Application

• Pharmaceutical Reference Standard: Used as a high-purity analytical standard for quality control and method development in drug discovery pipelines targeting polyphenolic actives.
• Nutraceutical & Functional Food Research: Serves as a key compound for studying the bioavailability, metabolism, and health benefits of complex tannins in dietary supplements.
• Cosmeceutical Ingredient Development: Investigated for its potent antioxidant properties in formulations aimed at skin protection against oxidative stress and UV-induced damage.
• Biochemical Research: Employed in enzymatic and receptor-binding assays to elucidate the mechanisms of action of ellagitannins and their metabolites.
• Natural Product Isolation & Authentication: Acts as a critical marker compound for the identification and standardization of botanical extracts rich in hydrolyzable tannins.

Quality Control

Our 3-o-Galloyl-2-o-[2-[[(5,10-Dihydro-3,7,8-Trihydroxy-5,10-Dioxo[1]Benzopyrano[5,4,3-Cde][1]Benzopyran)-2-Yl]Oxy]Galloyl]-D-Glucopyranose is produced and handled under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for research and development. Certificates of Analysis (COA) detailing purity, assay, and chromatographic data are available upon request to support your regulatory and quality assurance needs.

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 sensitivity to oxidation, long-term storage under an inert atmosphere (e.g., nitrogen or argon) is recommended for optimal stability. Keep the container tightly sealed in a desiccator to minimize exposure to atmospheric moisture.
