Quality Control

Our 5,8-Dihydroxy-3,7-Dimethoxyflavone is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity verification and spectroscopic methods for structural confirmation, to ensure it meets the high standards required for research and industrial use. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is 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 nature and propensity for oxidation, prolonged exposure to light, heat, or air should be avoided. For long-term storage, consider under an inert atmosphere.
