Quality Control

Our 7,8-Dihydroxy-4'-Methoxy Isoflavone is produced under strict quality management protocols. Each batch undergoes comprehensive 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 Certificate of Analysis (COA) detailing all specifications 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, prolonged exposure to light and air should be minimized. For long-term storage, consider under an inert atmosphere.
