Quality Control

Our 7,7'-Dihydroxy-4,4'-Dimethoxy-5,5'-Dimethyl-8,8'-Bi(2H-1-Benzopyran)-2,2'-Dione is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods, to ensure it meets exacting standards for research and development. Certificates of Analysis (COA) detailing batch-specific results are available upon request.

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 nature and propensity for oxidation, it is recommended to store the material under an inert atmosphere for long-term preservation. Keep away from incompatible materials.
