88-19-7 - Application:

o-Toluenesulfonamide (CAS: 88-19-7) is used to manufacture saccharin, plasticizers, adhesives, pesticide intermediates, pharmaceutical and other products. The plasticizer of thermosetting resin is used as raw material in organic synthesis, preparation of nail polish, dye, fluorescent pigment and coating.
o-Toluenesulfonamide was mainly produced as a chemical intermediate for the production of saccharin. A mixture of o-Toluenesulfonamide with the p-isomer is used as a plasticizer for hot -melt adhesives, a chemical intermediate for fluorescent pigments and a chemical intermediate for plasticizer resins. Studies suggest that o-Toluene sulfonamide has potential mutagenic activity. 

88-19-7 - Safety Profile:

Suspected carcinogen with experimental tumorigenic data. Mildly toxic by ingestion. Experimental reproductive effects. Mutation data reported. An eye irritant. When heated to decomposition it emits very toxic fumes of NOx and SOx. Used as a chemical intermediate in the production of saccharin.
