Quality Control

Our 5,6,4'-Trihydroxy-3,7-Dimethoxyflavone is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity verification and spectroscopic methods for structural confirmation, to ensure it meets the high standards required for research and development. A Certificate of Analysis (COA) detailing all test results is provided with every shipment.

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.
