Quality Control

Our 4-Chloro-3-Quinolinesulfonicacid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via IR and NMR spectroscopy, to ensure it meets exacting standards for research and development use. A comprehensive Certificate of Analysis (COA) detailing all specifications and test results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation. Keep away from incompatible materials such as strong bases and oxidizing agents.
