🇬🇧
/ˌθriːˌæmɪnəˈfɛnɒl/
amino group at position 3 on a phenol ring
Etymology
'3-aminophenol' originates from the numeral '3' (indicating the 3-position on the ring), combined with 'amino' (from 'amine', a chemical group name) and 'phenol' (the aromatic alcohol name 'phenol').
'phenol' was named in the 19th century from the radical 'phenyl' plus the alcohol suffix '-ol'; 'amino' derives from 'amine' (coined in modern chemistry from usage of 'ammonia' and related compounds). Combining locants (like '3-') with functional-group names produced systematic names such as '3-aminophenol'.
Initially the parts 'amino' and 'phenol' referred to functional groups; over time the combined systematic name '3-aminophenol' came to denote the specific compound with an amino group at the 3-position of phenol.
