/ˌnaɪn-ænˈθræsənɪl/

anthracene-derived radical at position 9

Etymology
Etymology Information

'9-anthracenyl' originates from systematic chemical nomenclature combining the prefix '9-' (indicating the 9-position) with 'anthracen' from 'anthracene' and the suffix '-yl' meaning 'radical' or 'substituent'.

Historical Evolution

'anthracene' comes from Greek 'anthrax' meaning 'coal' via New Latin and early organic-chemistry usage; the derivative form 'anthracenyl' (and positional forms such as 'anthracen-9-yl') developed later in organic nomenclature to denote radicals or substituents.

Meaning Changes

Initially the root 'anthracene' named an aromatic hydrocarbon commonly obtained from coal tar; over time derivatives named with the '-yl' suffix came to denote radicals or substituent groups derived from that parent hydrocarbon, which is the current meaning of '9-anthracenyl'.
