Quality Control

Our 4,5-Dichloro-2-Methylbenzenesulfonyl Chloride is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC, NMR, and GC-MS, to ensure identity, purity, and consistency. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment, guaranteeing it meets the stringent requirements for research and commercial synthesis.

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 nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and decomposition. Keep away from heat, open flames, and incompatible materials such as strong bases, amines, and alcohols.
