anthracene with two ketone groups at positions 9 and 10
Etymology
'9,10-anthracenedione' originates from Neo-Latin and systematic chemical nomenclature, constructed from 'anthracene' and the suffix '-dione', where 'anthracene' derives from Greek 'anthrax' meaning 'coal' and '-dione' indicates 'two ketone groups'.
'anthracene' was named in the 19th century from Greek 'anthrax' ('coal') because it is obtained from coal-tar; later chemical naming conventions combined this root with the suffix '-dione' to specify a diketone at positions 9 and 10, giving the systematic name '9,10-anthracenedione' alongside the common name 'anthraquinone'.
Initially the components of the name identified source ('anthracene') and functional groups; over time the systematic construction '9,10-anthracenedione' became a standardized way to specify the exact position of the two ketone groups and is used interchangeably with the common name 'anthraquinone'.
