9-anthracyl
|9-an-thra-cyl|
/ˌnaɪn-ænˈθræsɪl/
9-position anthracene substituent
Etymology
'9-anthracyl' originates from the locant '9' (indicating the ninth carbon) combined with 'anthracyl'. 'anthracyl' itself derives from 'anthracene', which ultimately comes from Greek 'anthrax', where 'anthrax' meant 'coal'. The chemical suffix '-yl' comes from Neo-Latin/International scientific usage denoting a radical or substituent.
'anthracyl' changed from the hydrocarbon name 'anthracene' (entered English via French and Latin from Greek) to form the substituent name 'anthracyl'; adding the locant produced the specific substituent name '9-anthracyl'.
Initially, the root referred to the coal-derived hydrocarbon 'anthracene'; over time the formation 'anthracyl' came to denote the radical or substituent derived from that hydrocarbon, and '9-anthracyl' specifies derivation at the 9-position.
