DMST Usage And Synthesis

Uses

4-Dimethylaminosulfotoluidide is an intermediate in the synthesis of Tolylfluanide (T536730), a polyvalent sulfamide fungicide that is closely related to dichlofluanide.

Definition

ChEBI: A member of the class of sulfamides that is N,N-dimethylsulfuric diamide substituted by a 4-methylphenyl group at the amino nitrogen atom. It is a metabolite of the agrochemical tolylfluanid.
