The sulfonic acid derivatives of 1-naphthylamine are used for the preparation of azo dye.These compounds possess the important property of dyeing unmordanted cotton.. An important derivative is naphthionic acid (1-aminonaphthalene-4-sulfonic acid), which is produced by heating 1-naphthylamine and sulfuric acid to 170–180 °C in the presence of crystallized oxalic acid.
reduction of 1-nitroonaphthalene-8-sulfonic acid, precursor to C.I. Acid Blue 113 Notes: Peri-acid dehydrates to the sultam . Via the Bucherer reaction , heating periacid with anilinium salts gives the N-phenyl derivative, precursor to Acid Blue 113.
N,N-Dimethyl-1-naphthylamine is an aromatic amine. It is formally derived from 1-naphthylamine by replacing the hydrogen atoms on the amino group with methyl groups. N,N-Dimethyl-1-naphthylamine is used in the nitrate reductase test to form a precipitate of a red azo dye by reacting with a nitrite-sulfanilic acid complex. [3]
