3,5-Dichlorobenzenesulfonyl chloride Chemical Properties, Uses, Production
Chemical Properties
beige low melting solid
Uses
Based on the study using 2,5-dichlorobenzenesulfonyl chloride, 3,5-dichlorobenzenesulfonyl chloride may act as a crosslinking agent for polyamides. It could react with –NH groups to enhance thermal stability (non-melting up to 1000°C), flame retardancy, and chemical resistance, though mechanical strength may decrease.[1]
