3,4-Dichlorobenzenesulfonyl chloride(CAT: L011438) is an organosulfur compound with two chlorine atoms at the 3- and 4-positions of a benzene ring and a sulfonyl chloride (-SO₂Cl) functional group attached. This compound is widely used in organic synthesis, especially in the production of sulfonamides, sulfonylureas, and other sulfonyl derivatives. The sulfonyl chloride group is highly reactive and can readily undergo substitution reactions with nucleophiles such as amines or alcohols, making it a useful intermediate for synthesizing pharmaceuticals, agrochemicals, and dyes. Its chlorinated benzene ring also provides increased stability and influences the reactivity of the molecule, making it suitable for creating complex chemical structures.
