aromatic amine with an amino group at position 4
Etymology
'4-aminodiphenylamine' is a systematic chemical name formed from the numeric locant '4' (indicating position), the prefix 'amino' (from 'amine'), and 'diphenylamine' (meaning two phenyl rings attached to an amine). 'amino' ultimately derives from 'amine' which is related to 'ammonia'.
'amine' was coined in the 19th century from 'ammonia' (through modern chemical nomenclature); 'phenyl' comes from 'phenol' with Greek roots 'pheno-' meaning 'to show or emit' (via chemical naming conventions); combining these parts produced the systematic modern English chemical name '4-aminodiphenylamine'.
Initially, components like 'amine' referred broadly to derivatives of ammonia; over time the term became specialized to denote organic nitrogen-containing functional groups, and the composite systematic name now specifically denotes the substituted diphenylamine described above.
