Quality Control

Our 3(3',4'-Dimethoxyphenyl)-7-Hydroxy-4-Phenylcoumarin is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods, to ensure it meets the stringent requirements of research and process chemistry. A Certificate of Analysis (COA) detailing all specifications is provided with each 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 material under an inert atmosphere (e.g., nitrogen or argon) for long-term stability, especially after the original container is opened.
