4-AMINO-6-CHLORO-BENZENE-1,3-DISULFONYL DICHLORIDE Usage And Synthesis

Chemical Properties

Brown Solid

Uses

Chlorothiazide intermediate.

Production Methods

4-Amino-6-chloro-1,3-benzenedisulfonyl Chloride is obtained by chlorosulfonation of 3-chloroaniline with 11 mol of chlorosulfuric acid at 130 ℃; after the chlorosulfonation mixture is treated with 4 mol of thionyl chloride at 80 ℃, the yield is 90 %.
