Quality Control

Our 3,4-Dimethoxy-3,5,7-Trihydroxyflavone is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods (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 to support your quality assurance protocols.

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 light-sensitive nature and propensity to be easily oxidized, prolonged exposure to light, air, or elevated temperatures should be avoided to maintain stability and purity. For long-term storage, consider an inert atmosphere.
