Quality Control

Our 3,7-Dihydroxy-3',4',5'-Trimethoxyflavone is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods (IR, NMR, MS), to ensure it meets the high standards required 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 place at a controlled room temperature (typically 15-25°C). This compound is light-sensitive (store away from light) and may be hygroscopic (moisture-sensitive); therefore, the container should be kept tightly sealed in a dry environment.
