2-Naphthylamine CAS 91-59-8 Purity >98.0% (HPLC)

2-Naphthylamine (CAS: 91-59-8) 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. It is insoluble in water, but soluble in hot water, ethanol, ether and benzene etc. Aqueous solution is blue fluorescence. It can be reducted by heat silver nitrate ammonia solution. It is synthesized by 2-naphthol with ammonia and ammonium sulfite in a high pressure system. 2-Naphthylamine is an important dye intermediates, can be used in the manufacture of dyes, phthalocyanine dyes, reactive dyes (Reactive brilliant orange K-7R, active golden XG, active golden KM-G, Reactive Yellow KM-RN, big red group B) and J acid. It can also be used as organic analytical reagents and fluorescent indicator, and also as a synthesis of organic materials. 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. It is listed as a known human carcinogen. Used in manufacturing of dyes, as antioxidant in rubber. It is as an intermediate in the preparation of other compounds. Its use is curtailed because of thehealth hazard. Production equipment should be tightly closed to prevent the escape of toxic vapors and dusts.
