Quality Control

Our 2''-(3,4-Dihydroxyphenyl)-3,3',3'',4,4',4''-Hexahydro-2,2'-Bis(3,4,5-Trihydroxyphenyl)-4,8':4',8''-Ter(2H-1-Benzopyran)-3,3',3'',5'',7,7',7''-Heptol is produced under a strict quality management system. Each batch is characterized and tested using advanced analytical techniques including HPLC, MS, and NMR to ensure structural identity and purity. A comprehensive Certificate of Analysis (COA) detailing purity, impurities, and analytical results is provided with every shipment to support your regulatory and research 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 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 dry environment to minimize exposure to moisture.
