Product Name:4-Chlorobenzenesulfonic acid
English Name:4-Chlorobenzenesulfonic acid
CAS No.:98-66-8
Aliases:p-Chlorobenzenesulfonic acid, 4-Chlorobenzenesulfonic acid hydrate, p-Chlorobenzenesulphonic acid
Molecular Formula:C6H5ClO3S
Physical Properties:White to off-white crystalline powder; molecular weight 192.62; melting point 102°C; boiling point 149°C (with decomposition); relative density 1.551. Soluble in water, ethanol and ether; aqueous solution is strongly acidic. Hygroscopic and corrosive, irritating to skin and eyes; thermal decomposition releases sulfur oxides and hydrogen chloride gas. Transport information: UN 2583, hazard class 8, packing group III, hazard codes R22/R34, safety code S24/25. Keep container closed and store in a cool, dry and well-ventilated area, away from incompatible and corrosive materials.
Uses:Used as an intermediate in pharmaceuticals and dyes. In organic synthesis, it is used to prepare p-chlorobenzenesulfonamide, sulfonate esters and surfactants, as well as in the production of pesticides and ion-exchange resins.
Technical Specifications:
Content (as C6H5ClO3S) ≥98%
Melting point: 101–104°C
Loss on drying: ≤1.0%
Appearance: white to off-white crystalline powder
Packaging: 1kg, 10kg, 25kg
