Quality Control

Our 3,3',4',5,7-Pentahydroxy-6-Methylflavone is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, IR and NMR for structural confirmation, and residual solvent analysis. We provide Certificates of Analysis (COA) with each shipment to ensure traceability and compliance with your research or production standards. Specifications can be tailored to meet specific project requirements, including higher purity grades for pharmaceutical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, prolonged exposure to light, air, or elevated temperatures should be avoided. For long-term storage, consider keeping the material under an inert atmosphere such as argon or nitrogen.
