General description

N,N-Dimethyl-1-naphthylamine is an aromatic amine and a dye.

Application

N,N-Dimethyl-1-naphthylamine (1-Dimethylaminonaphthalene) is used to study nitrate reduction by organisms. Reduction of nitrate results in the formation of nitrite, which reacts with sulfanilic acid and 1-dimethylaminonaphthalene to form a red diazo dye.
