Forms: 1800s nitro-anilin, 1800s– nitraniline Brit.

/ˌnʌɪˈtranᵻliːn/,

/ˌnʌɪˈtranl̩iːn/,

/ˌnʌɪˈtranᵻlɪn/,

/ˌnʌɪˈtranl̩ɪn/, U.S.

/ˌnaɪˈtrænələn/, 1800s– nitroaniline.

Origin: Formed within English, by compounding; perhaps modelled on a German lexical item. Etymons: nitro- comb. form, aniline n.

Etymology: < nitro- comb. form + aniline n., perhaps after German Nitranilin (1845, by the authors of quot. 1848, in Ann. der Chem. u. Pharm. 54 27; this is the German version of the paper read in London in April 1845 but not published in English until the following year). N.E.D. (1907) enters this under nitraniline and gives the pronunciation as (nəitræ·niləin) /naɪˈtrænɪlaɪn/.

Chemistry.

Each of three isomeric yellow or orange crystalline compounds, C₆H₄(NO₂)(NH₂), which are derivatives of aniline having a nitro group attached to the carbon ring, and are used in the manufacture of dyes; nitrophenylamine. N-nitroaniline n. a pearly-white crystalline compound, NO₂NHC₆H₅, isomeric with nitroaniline, but with the nitro group attached to the amine group; phenylnitramine.
