N,N-Dimethyl-1-naphthylamine Usage And Synthesis

Chemical Properties

light yellow liquid

Uses

N,N-Dimethyl-1-naphthylamine is used in the nitrate reductase test to form a red precipitate of Prontosil by reacting with a nitrite-sulfanilic acid complex. And is also used to detection and determination of nitrites.

Uses

Detection and determination of nitrites.

Biological Activity

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.

Safety Profile

Poison by intraperitoneal route. Moderately toxic by ingestion. Mutation data reported. When heated to decomposition it emits toxic fumes of NOx
