Quality Control

Our 5,7-Dihydroxy-3-Methoxy-2-(4-Methoxy-Phenyl)-Chromen-4-One is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation (IR, NMR), to ensure it meets high-grade specifications suitable for research and development. Certificates of Analysis (COA) documenting all critical parameters 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 (15-25°C). This product is light-sensitive (store away from light) and easily oxidized (store under inert atmosphere); therefore, containers should be kept sealed under an inert gas blanket when possible and opened only in a controlled environment.
