| N-Methyl-N-nitrosotoluene-4-sulphonamide Usage And Synthesis |
| Chemical Properties | pale yellow crystalline powder |
| Uses | In the laboratory preparation of diazomethane. Directions for use: de Boer, Backer, Rec. Trav. Chim. 73, 232 (1954). |
| Uses | N-Methyl-N-nitroso-p-toluenesulfonamide is Diazomethane precursor. |
| Definition | ChEBI: N,4-dimethyl-N-nitrosobenzenesulfonamide is a sulfonamide. |
| Purification Methods | Crystallise diazald from *benzene by addition of pet ether and store it in a refrigerator. It is soluble in most organic solvents and liberates diazomethane on treatment with alkali. Store it in the cold. [deBoer & Backer Org Synth 34 96 1954, Beilstein 11 I 29.] |
