Quality Control

Our 3H-Pyrido[3,2,1-Kl]Phenoxazine-2-Carboxylicacid,6-[3-[[(1,1-Dimethylethoxy)Carbonyl]Amino]-1-Pyrrolidinyl]-5-Fluoro-3-Oxo-,Ethylester(9Ci) is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for pharmaceutical R&D and cGMP manufacturing. A comprehensive Certificate of Analysis (COA) detailing purity, impurities, and other critical parameters 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 hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider using desiccants.
