o-Chlorobenzenesulfonamide Usage And Synthesis

Uses	2-Chlorobenzenesulfonamide may be used in the synthesis of 2-chloro-N-(4-methoxybenzoyl)benzenesulfonamide and 1,2,4-thiadiazine ,1-dioxides.
General Description	2-Chlorobenzenesulfonamide is a halogenated sulfonamide derivative. It is formed as one of the major degradation product of chlorosulfuron. Crystals of 2-chlorobenzenesulfonamide exhibit monoclinic space group Cc. Its molecules are linked by N1—H11···O1 and N1—H12···O2 hydrogen bonding to form an infinite 3-D molecular network.
