Description

pale yellow crystalline powder

N,4-dimethyl-N-nitrosobenzenesulfonamide is a sulfonamide.

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.]

N-Methyl-N-nitrosotoluene-4-sulphonamide Use and Manufacturing

Methods of Manufacturing

Dissolve N-methyl-p-toluenesulfonamide in glacial acetic acid, cool to 5°C, dropwise add an aqueous solution of sodium nitrite, and the reaction precipitates yellow N-methyl-N-nitroso-p-toluenesulfonamide. N-methyl p-toluenesulfonamide is obtained by reacting p-toluenesulfonyl chloride with methylamine.

Uses

In the laboratory preparation of diazomethane.Directions for use:de Boer, Backer, Rec. Trav. Chim. 73, 232 (1954).

N-Methyl-N-nitroso-p-toluenesulfonamide is Diazomethane precursor.
