Quality Control

Our 3,4'-Dimethoxy-3',5,7-Trihydroxyflavone is produced and tested under a rigorous quality management system. Each batch is analyzed to ensure identity, purity, and consistency, meeting the high standards required for research and development applications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment.

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 nature and propensity for oxidation, it is recommended to handle under an inert atmosphere for long-term storage and to minimize headspace in opened containers.
