Quality Control

Our 3,5,7-Trihydroxy-2H-1-Benzopyran-2-One is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC and spectroscopic methods, to ensure it meets high-purity standards suitable for research and industrial use. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, it is recommended to handle under an inert atmosphere for long-term storage and to minimize exposure to air and moisture.
