Quality Control

Our 3,5,4''-Trihydroxy-7-Methoxyflavone is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation (IR, MS), to ensure it meets stringent specifications for research and pharmaceutical use. A detailed Certificate of Analysis (COA) is provided with each shipment, guaranteeing traceability and compliance with relevant 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 light-sensitive and easily oxidized nature, prolonged exposure to light, air, or elevated temperatures should be avoided to maintain stability and purity. For long-term storage, consider an inert atmosphere.
