Quality Control

Our 5,7-Dihydroxy-3-(5-Hydroxy-2,2-Dimethyl-2H-1-Benzopyran-6-Yl)-4H-1-Benzopyran-4-One is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods, to ensure it meets precise customer specifications and high-purity standards. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment.

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 sensitivity to oxidation, long-term storage under an inert atmosphere (e.g., nitrogen or argon) is recommended for optimal stability. Keep away from strong oxidizing agents.
