The ketone form of anthracene derivatives, containing a carbonyl group bonded to the anthracene structure.
From anthracene + '-one' (ketone suffix). The '-one' ending indicates a carbon-oxygen double bond (C=O), the signature of a ketone.
The '-one' suffix appears in acetone, cortisone, and ketones your body burns during fasting—it's one of chemistry's most recognizable functional group indicators!
