meta-methoxyaniline (methoxy at 3-position)
Etymology
'm-anisidine' is formed from the prefix 'm-' (short for 'meta-') and the base name 'anisidine'. 'Anisidine' derives from 'anis-' (from Latin 'anisum', meaning 'anise') combined with the chemical suffix '-idine'/'-ine' used for nitrogen-containing organic compounds.
'anisidine' originated in Neo-Latin and chemical nomenclature (related to 'anisole' and products historically associated with anise/oil of anise), and the modern systematic name 'm-anisidine' (or 'meta-anisidine') developed to specify the substitution pattern (meta/3-position) on the benzene ring.
Initially, names like 'aniside/anisidine' reflected associations with anise or anisole-like substances; over time the term became a standardized chemical name referring specifically to methoxy-substituted aniline isomers, with 'm-' indicating the meta position.
