N-Methyl-N-nitroso-p-toluenesulfonamide is Diazomethane precursor.
The Uses of N-Methyl-N-nitrosotoluene-4-sulphonamide
In the laboratory preparation of diazomethane. Directions for use: de Boer, Backer, Rec. Trav. Chim. 73, 232 (1954).
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.]
