Quality Control

Our 3-o-Methylquercetin is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods, to ensure it meets high-purity standards suitable for research and development. A comprehensive Certificate of Analysis (COA) detailing purity, impurities, and analytical results 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 and easily oxidized nature, it is recommended to store the product under an inert atmosphere for long-term preservation and to minimize exposure to air and moisture upon opening.
