Chloramine-T is an N-terminally chlorinated and N-terminally deprotonated sulfonamide used as an insecticide and mild disinfectant.
Prismatic crystal, soluble in water, almost insoluble in benzene, chloroform and ether. Decay in ethanol. There is no certain melting point, as well as it is violently decayed (exploded) at 175-180 ??. With minor chlorine scent, it progressively sheds water in dry air, and slowly decomposes in exposed air to launch chlorine.
Chloramine-T can be prepared in a return of 75?C 95% by presenting chlorine into the salt hydroxide option of p-toluenesulfonamide. It is a solid electrolyte in acid remedy and a great oxidant in alkali option. Conveniently soluble in water, nearly insoluble in benzene, chloroform and ether. The substance can conveniently react with mustard gas to generate safe crystalline thioimides; Chloramine-T derivatives are being studied as poison gas guards.
