Quality Control

Our 5,6-Dihydroxy-2-(3-Hydroxy-4,5-Dimethoxyphenyl)-3,7-Dimethoxy-4H-1-Benzopyran-4-One is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for research and development. Certificates of Analysis (COA) with detailed chromatographic data are available upon request to support your quality assurance and regulatory documentation.

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, it is recommended to store the material under an inert atmosphere for long-term stability. Keep the container tightly sealed in a dry environment to minimize exposure to moisture.
