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.
Naphthylamine or aminonaphthalene can refer to either of two isomeric chemical compounds: 1-Naphthylamine (1-aminonaphthalene) 2-Naphthylamine (2-aminonaphthalene)
N-(1-Naphthyl)ethylenediamine dihydrochloride is widely used in the quantitative analysis of nitrate and nitrite in water samples by colorimetry. It readily undergoes a diazonium coupling reaction in the presence of nitrite to give a strongly colored azo compound .
1-Nitronaphthalene is an organic compound with the formula C 10 H 7 NO 2. It is one of two isomers of nitronaphthalene. A pale yellow, sublimable solid, 1-nitronaphthalene is the main product of the direct nitration of naphthalene. It is an intermediate in the production of naphthylamine, a precursor to dyes. [1]
