N-Methyl-N-nitrosotoluene-4-sulphonamide Usage And Synthesis

Chemical Properties	pale yellow crystalline powder
Uses	N-Methyl-N-nitroso-p-toluenesulfonamide is Diazomethane precursor.
Uses	In the laboratory preparation of diazomethane. Directions for use: de Boer, Backer, Rec. Trav. Chim. 73, 232 (1954).
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.]
