Quality Control

Our 4',7-Dimethoxy-3,3',5-Trihydroxyflavone is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity verification and spectroscopic methods for structural confirmation, to ensure it meets the high standards required for research and development. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request to support your regulatory and quality assurance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (typically 15-25°C). Due to its light-sensitive nature and propensity for oxidation, prolonged exposure to light, heat, or air should be avoided to maintain stability and purity.
