Quality Control

Our 7-(β-D-Galactopyranosyloxy)-3,3',4',5-Tetrahydroxyflavone is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation (IR, NMR), to ensure it meets the high standards required for research and development. Certificates of Analysis (COA) documenting all critical parameters are available upon request.

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 light and tendency for oxidation, it is recommended to handle under an inert atmosphere for long-term storage and to minimize headspace in opened containers.
