/ˌærɪˈleɪmiːn/

amine attached to an aromatic (aryl) ring

Etymology
Etymology Information

'arylamine' is a modern chemical formation combining the element 'aryl' and 'amine'. 'Aryl' was coined in organic chemistry as a contraction of 'aromatic' + the suffix '-yl' (denoting a radical), while 'amine' comes from French 'amine', ultimately related to 'ammonia'.

Historical Evolution

'arylamine' emerged in late 19th to early 20th-century chemical nomenclature by joining 'aryl' (a 19th-century term formed from 'aromatic' + '-yl') and 'amine' (a term derived from the name 'ammonia' used for nitrogen-containing bases).

Meaning Changes

Initially, 'amine' referred broadly to derivatives of ammonia; over time 'arylamine' came to denote specifically those amines in which the amino group is attached to an aryl (aromatic) ring.

Meanings by Part of Speech

Noun 1

a compound in which an amino group (−NH2 or substituted −NR2) is directly bonded to an aryl (aromatic) ring; an aromatic amine.

An arylamine typically has different reactivity from an aliphatic amine because the amino group is conjugated with the aromatic ring.
