2-Naphthylamine is one of two isomeric aminonaphthalenes, compounds with the formula C10H7NH2. It is a colorless solid, but samples take on a reddish color in air because of oxidiation. The aromatic amine used to be used to make azo dyes. It is a known carcinogen and has largely been replaced by less toxic compounds. 2-Naphthylamine is also known as β-Naphthylamine, it is white to pink shiny flaky crystal, it is volatile with water vapor. It is harmful, carcinogenic, the International Institute for Cancer Research (IARC) put benzidine, 2-Naphthylamine and 4-aminobiphenyl as a human carcinogen (evidence), we should be particularly careful. The relative density is 1.0614 (98/4℃), m.p. is 111~113℃, boiling point is 306℃. It is insoluble in water, but soluble in hot water, ethanol, eth-er and benzene etc. Aqueous solution is blue fluorescence. Amino and nitrite of Aminonaphthalene can form diazonium salt, and can turn into a variety of hydrocarbon derivatives of naphthalene, it can be used in the manufacture of dyes and organic synthesis, also used as indicators of organic analytical reagents and fluorescent agents.
