Quality Control

Every batch of our 4-O-[[(aS)-2-[(5,10-Dihydro-2,3,7,8-tetrahydroxy-5,10-dioxo[1]benzopyrano[5,4,3-cde][1]benzopyran)-1-yl]-3,4,5-trihydroxyphenyl]carbonyl]-6-O-(3,4,5-trihydroxyphenylcarbonyl)-β-D-glucopyranose is manufactured and analyzed under a strict quality management system. We provide comprehensive analytical documentation, including a detailed Certificate of Analysis (COA) with data from HPLC, NMR, and MS to confirm identity and purity. Our quality protocols are designed to meet the exacting standards required for research and development applications.

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.
