Quality Control

Our 4H-1-Benzopyran-4-One,2-(3,4-Diaminophenyl)-(9Ci) is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and MS, to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting all critical parameters are available upon request. We can supply material tailored to meet specific research or cGMP intermediate requirements.

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 sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from incompatible materials such as strong oxidizing agents.
