/ˌəʊ.mɛθəksiˈbɛn.zɔɪl/
benzoyl group with a methoxy substituent (ortho/oxygen-linked nuance)
Etymology
'O-methoxybenzoyl' is a systematic chemical name composed of three parts: the prefix 'O-' (denoting linkage at an oxygen atom or, in some contexts, indicating oxygen substitution), 'methoxy' (from 'methyl' + 'oxy', indicating an -OCH3 substituent), and 'benzoyl' (an acyl group derived from benzoic acid).
'benzoyl' originates from 'benzoin' (a resinous substance) via New Latin and French; 'benzoin' itself has roots in Arabic and Malay terms for aromatic resin. 'Methoxy' is formed from 'methyl' (coined in the 19th century from Greek 'methy' for wine, via 'methyl') plus the combining form 'oxy' from Greek 'oxys' meaning 'sharp' or related to oxygen. The assembled modern systematic form 'O-methoxybenzoyl' developed as organic nomenclature became more standardized in the 19th and 20th centuries.
Originally, components like 'benzoyl' referred broadly to derivatives of benzoin or benzoic acid; over time they acquired the precise structural meaning used in modern organic nomenclature — here referring specifically to an acyl group (benzoyl) substituted by a methoxy group at a defined position.
Meanings by Part of Speech
Noun 1
a benzoyl substituent in which a methoxy group is present on the aromatic ring at the ortho position (often written 'o-methoxybenzoyl' or '2-methoxybenzoyl'); used to denote a specific acyl group in organic chemistry.
The synthesis required introduction of an O-methoxybenzoyl group at the ortho position of the aromatic ring.
