🇬🇧
/fɔːˌmɛθɒksiˈænɪliːn/
aniline with a methoxy group at the 4 (para) position
Etymology
'4-methoxyaniline' originates from modern chemical nomenclature (IUPAC-style naming), combining the locant '4-' (indicating the para position), 'methoxy' (derived from 'methyl' + 'oxy', denoting an –OCH3 substituent) and 'aniline' (the parent aromatic amine).
'aniline' entered English via French 'aniline', ultimately from Portuguese 'anil' (from Arabic 'al-nīl', meaning 'indigo'); 'methoxy' was formed in 19th-century chemical nomenclature from 'methyl' + 'oxy'; numeric locants like '4-' are part of modern systematic nomenclature developed in the 19th–20th centuries and standardized by IUPAC.
Initially, terms related to 'anil' referred to indigo or substances derived from indigo; over time 'aniline' became the established name for the specific aromatic amine, and '4-methoxyaniline' now specifically denotes the aniline bearing a methoxy group at the 4-position.
