| Physical properties | 5-Chloro-2-nitrobenzenesulfonic Acid, forms hygroscopic crystals of the monohydrate. | | Uses | Reduction of 5-Chloro-2-nitrobenzenesulfonic acid gives 4-chloroaniline-2-sulfonic acid, and amination results in 4- nitroaniline-3-sulfonic acid, both of minor importance as intermediates. The derived sulfonyl chloride leads to 5-chloro-2-nitrobenzenesulfonamide, an intermediate in the production of the benzothiadiazine derivative diazoxide, used as a vasodilator. | | Production Methods | 5,5' -Dichloro-2,2' -dinitrodiphenyldisulfide (obtained from the reaction of 2,4-dichloronitrobenzene with Na2S2) is oxidatively chlorinated with chlorine in HCl – HNO3 to give the sulfonyl chloride, which hydrolyzes to 5-Chloro-2-nitrobenzenesulfonic acid. |
