Applications

N,N-Dimethylaniline acts as a precursor to triarylmethane dyes such as crystal violet and malachite green. It is also used in the synthesis of vanillin, methyl violet, and Michler's ketone. Further, it is used as a hardener for plastic resins and an acid scavenger in the manufacture of semisynthetic penicillins and cephalosporins. In addition to this, it is used as a promoter in the curing of polyester and vinyl ester resins.

Notes

Incompatible with strong oxidizing agents, Strong acids, acid chlorides, acid anhydrides, chloroformates and halogens.
