Quality Control

Our 3-Quinolinecarboxylic Acid, 1-Cyclopropyl-7-(4-Ethyl-1-Piperazinyl)-6-Fluoro-1,4-Dihydro-4-Oxo-, 2-[(2-Methoxyethyl)Amino]-2-Oxoethyl Ester is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and stringent control of residual solvents and impurities to meet the exacting standards required for pharmaceutical development. Certificates of Analysis (COA) with full traceability are provided for every shipment, ensuring compliance with cGMP and ICH Q7 guidelines for active pharmaceutical ingredients.

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 hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed in a desiccated environment away from direct light exposure to maintain stability and purity.
