Description

CAS: 88-19-7 | C7H9NO2S | 171.214 g/mol

o-Toluene sulfonamide was mainly produced as a chemical intermediate for the production of saccharin. A mixture of o-Toluene sulfonamide 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. (S080800). Studies suggest that o-Toluene sulfonamide has potential mutagenic activity.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
