🇬🇧
/ˌtuːˌeɪˌæmɪˈnəʊˌfɛnəl/
phenol with an amino group at the 2-position
Etymology
'2-aminophenol' originates from systematic chemical nomenclature combining the locant '2', 'amino' (from 'amine', itself named with reference to 'ammonia') and 'phenol' (from 'phenyl' + the suffix '-ol' for alcohol derivatives).
'amino' was coined in the 19th century from 'amine' (linked to 'ammonia'), and 'phenol' was coined in the 19th century from 'phenyl' + '-ol'; these element names were later combined in modern organic nomenclature (IUPAC-style) to form names such as '2-aminophenol'.
Initially the component words referenced 'ammonia-related' and 'phenyl alcohol' concepts; over time they were standardized as functional-group names in organic chemistry, so the combined name now specifically denotes a phenol bearing an amino substituent at the 2-position.
