| Hazard Information | Back Directory | [Chemical Properties]
2-Methylbenzene-1-sulfonamide is Colorless crystals. Soluble in alcohol; slightly soluble in water and ether. Combustible.
| [Uses]
2-Methylbenzene-1-sulfonamide is a methylated sulfonamide and a major Impurity if Saccharin (S080800). Studies suggest that o-Toluenesulfonamide has potential mutagenic activity.
| [Uses]
Plasticizer of thermosetting resin, as a raw material used in organic synthesis, preparation of nail polish, dyes, fluorescent pigments and coatings.
| [General Description]
Pharmaceutical secondary standards for application in quality control provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards. o-Toluenesulfonamide is a major impurity in artificial sweetening substances containing saccharin. | [Purification Methods]
Crystallise the amide from hot H2O (m 153o), then from EtOH or Et2O/pet ether. The N-o-toluenesulfonylphthalimide has m 182o (from EtOH). [Evans & Dehn J Am Chem Soc 51 3652 1929, Beilstein 11 H 86, 11 I 23, 11 II 39, 11 III 167, 11 IV 229.] |
