Trihydroxyanthraquinone
A trihydroxyanthraquinone or trihydroxyanthracenedione is any of several isomeric organic compounds with formula C
14H
8O
5, formally derived from anthraquinone by replacing three hydrogen atoms by hydroxyl groups. They include several historically important dyes.[1][2] The isomers may differ in the parent anthraquinone isomer and/or of the three hydroxyl groups.
In general there are 56 ways of choosing three out of the 8 hydrogens. However, if the underlying core is symmetrical, some of these choices will give identical molecules.
Isomers[]
From 9,10-anthraquinone[]
Due to the symmetry of the 9,10-anthraquinone core, there are only 14 isomers.[3]
- (anthragallol)[2]
- 1,2,4-Trihydroxyanthraquinone (purpurin), a component of madder root dye.
- (oxyanthrarufin)
