Quality Control

Every batch of 2-Bromo-4,6-Dichlorobenzenesulfonyl Chloride is produced and tested under a stringent quality management system to ensure batch-to-batch consistency and high purity. Our standard analytical controls include identity confirmation by FT-IR and NMR, purity determination by HPLC, and specific tests for key impurities. A comprehensive Certificate of Analysis (COA) detailing all test results and specifications is provided with each shipment to support your quality assurance protocols.

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 under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation from atmospheric moisture. Keep away from heat, sparks, open flames, and incompatible materials such as strong bases, amines, and alcohols.
