Quality Control

Every batch of our 2,2'-Bis(4-Methoxyphenyl)-5,5'-Dihydroxy-7,7'-Dimethoxy-8,8'-Bi(4H-1-Benzopyran)-4,4'-Dione undergoes rigorous analytical testing to ensure identity, purity, and consistency. Our quality assurance protocols are designed to meet the stringent requirements of research and industrial applications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to guarantee traceability and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its light-sensitive nature and propensity for oxidation, prolonged exposure to light or air should be avoided. For long-term storage, consider an inert atmosphere.
