Quality Control

Our 3,5-Bis(Chlorosulphonyl)Benzoyl Chloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation by FT-IR and NMR, to ensure it meets precise customer specifications. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and reacts with water and strong bases; ensure containers are kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) for long-term storage. Keep away from heat, open flames, and incompatible materials.
