Quality Control

Our 3,3',7-Trihydroxy-4'-Methoxyflavone is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity assay and identity confirmation via spectroscopic methods (IR, UV). We provide a detailed Certificate of Analysis (COA) with every shipment, ensuring traceability and compliance with your research or production specifications.

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 potential for oxidation, prolonged exposure to light, heat, or air should be avoided. For long-term storage, consider an inert atmosphere.
