Quality Control

Our 3-Chloro-4-(3-Pyridin-2-Yl-Ureido)-Benzenesulfonyl Chloride Hydrogen Sulfate is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for pharmaceutical R&D. Certificates of Analysis (COA) with detailed specifications are provided for each shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated 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. Keep away from incompatible materials such as strong bases and amines.
