Quality Control

Our 1-Chloro-4-[(dichloromethyl)sulfonyl]benzene is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure high purity and consistency, meeting the stringent requirements of our industrial and research partners. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to guarantee traceability and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (typically 15-25°C). Keep away from heat, sparks, and open flame. Due to the reactive nature of the sulfonyl chloride group, it should be stored separately from strong bases, amines, and alcohols.
