Quality Control

Every batch of 3,4-Dihydro-8-Hydroxy-3-(3-Hydroxy-4-Methoxyphenyl) 1H-2-Benzopyran-1-One is manufactured under a strict quality management system. Our products undergo rigorous analytical testing, including HPLC, NMR, and mass spectrometry, to ensure identity, purity, and consistency meet the high standards required for research and industrial use. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment and is available upon request.

Storage

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