Quality Control

Our 3',4',5,7-Tetrahydroxyisoflavone is produced and tested under a strict quality management system. We offer various purity grades, including high-purity standards suitable for research and pharmaceutical development. Each batch undergoes rigorous analytical testing, including HPLC for assay and purity verification. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurities is provided with every shipment to ensure traceability and compliance with your 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 and easily oxidized nature, it is recommended to store the product under an inert atmosphere (e.g., nitrogen or argon) for long-term stability, especially for high-purity grades. Keep away from strong oxidizing agents.
