Hydroxyanthraquinone
Encyclopedia
A hydroxyanthraquinone is any of several organic compound
s with formula C14H9O2(OH), which can be viewed as derivatives of an anthraquinone
through replacement of one hydrogen
atom (H) by an hydroxyl
group (-OH).
The IUPAC nomenclature recommends hydroxyanthracenedione.
Usually "hydroxyanthraquinone" refers to a derivative of 9,10-anthraquinone
.
(mono-, di-, tri-, up to octa-). Additional hydroxy- compounds can be derived from the other isomers of the latter. From 9,10-anthraquinone, only two single-hydroxy derivatives are possible.
Organic compound
An organic compound is any member of a large class of gaseous, liquid, or solid chemical compounds whose molecules contain carbon. For historical reasons discussed below, a few types of carbon-containing compounds such as carbides, carbonates, simple oxides of carbon, and cyanides, as well as the...

Hydroxyl
A hydroxyl is a chemical group containing an oxygen atom covalently bonded with a hydrogen atom. In inorganic chemistry, the hydroxyl group is known as the hydroxide ion, and scientists and reference works generally use these different terms though they refer to the same chemical structure in...

Isomers
Generally, the term may mean any anthraquinone derivative where any number n of hydrogens have been replaced by n hydroxyls, so that the formula is . In this case the number n (which is between 1 and 8) is indicated by a multiplier prefixPrefix
A prefix is an affix which is placed before the root of a word. Particularly in the study of languages,a prefix is also called a preformative, because it alters the form of the words to which it is affixed.Examples of prefixes:...
