naphthylaminen.

Brit.

/nafˈθʌɪləmiːn/,

/napˈθʌɪləmiːn/, U.S.

/ˌnæpˈθaɪləˌmin/,

/ˌnæfˈθaɪləˌmin/

Forms: 1800s– naphthylamin, 1800s– naphthylamine, 1800s– naphtylamine, 1900s– napthylamine.

Origin: Formed within English, by compounding. Etymons: naphthyl n., amine n.

Etymology: < naphthyl n. + amine n.With form naphtylamine compare forms s.v. naphthyl n. and French naphtylamine (1874).

Chemistry.

Either of two isomeric crystalline amines, C₁₀H₇NH₂, derived from naphthalene and used in the manufacture of certain dyes.Only the form naphthylamine is current. The β isomer is a powerful bladder carcinogen.

1856–7 Proc. Royal Soc. 8 49 This substance we term nitrosonaphthyline. It may likewise be obtained by the action of nitrous acid on naphthylamine.

1859–60 Proc. Royal Soc. 10 500 Even now the group of diacid diamines is represented in the naphtyl-series: Naphtylamine..monoacid. Naphtylenediamine..diacid.

1884 Athenæum 26 Mar. 433/1 Some sulphanilic acid with some hydrochlorate of naphthylamin added.

1911 Bot. Gaz. 52 18 The test [for nitrates] was made with equal parts of sulphanilic acid and napthylamine solution.

1924 Science 15 Aug. 145/2 In the cell of α-naphthylamin at least three molecules go to [make up] a part.

1971 Brit. Med. Bull. 27 29/2 Chlornaphazine..is metabolized to β-naphthylamine.

1999 Nature 30 Sept. 425/2 New cases of bladder cancer (by the 1920s suspected of being caused by β-naphthylamine and benzidine) continued to appear in the [German] dye industry.
