Quality Control

Our (S)-2,3-Dihydro-5,7-Dihydroxy-2-(2-Methoxyphenyl)-4H-1-Benzopyran-4-One is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity verification by HPLC, to ensure high chemical and isomeric purity suitable for research and development. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are provided with every shipment to guarantee traceability and batch-to-batch consistency.

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 material under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat and incompatible materials.
