Quality Control

Our [(2R,3R,4R)-2-(3,4-dihydroxyphenyl)-4-[(2R,3R)-2-(3,4-dihydroxyphenyl)-5,7-dihydroxy-3-(3,4,5-trihydroxybenzoyl)oxy-chroman-8-yl]-5,7-dihydroxy-chroman-3-yl] 3,4,5-trihydroxybenzoate is manufactured under strict quality management systems. Each batch is subjected to comprehensive analytical testing, including HPLC, NMR, and MS, to ensure identity, purity, and consistency. We provide a detailed Certificate of Analysis (COA) with every shipment, confirming compliance with customer specifications and relevant research-grade standards.

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 hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a desiccated environment to prevent degradation. For long-term storage, consider inert gas purging.
