anthrone with two hydroxy groups at positions 1 and 8

Etymology
Etymology Information

'1,8-dihydroxy-9-anthrone' originates from systematic chemical nomenclature: the numeric locants '1' and '8' indicate substitution positions, the prefix 'di-' means 'two', 'hydroxy' derives from 'hydroxyl' meaning an oxygen–hydrogen functional group, and 'anthrone' is the name of the anthracene-derived ketone core.

Historical Evolution

'anthrone' derives from 'anthracene' (from Greek 'anthrax' meaning 'coal') with the ketone-forming suffix '-one'; the modern name 'anthrone' developed in chemical nomenclature to denote the ketone analog of anthracene derivatives and is used in systematic names like '1,8-dihydroxy-9-anthrone'.

Meaning Changes

Initially, the root referred broadly to compounds related to anthracene; over time the term became a specific structural name for the ketone derivative now called 'anthrone', and the full systematic name now specifies exact substituent positions.
