2-Hydroxy-1,4-benzoquinone
Hydroxy-1,4-benzoquinone, also called hydroxy-''para''-benzoquinone, is an organic compound with formula , formally derived from 1,4-Benzoquinone by replacing one hydrogen atom with a hydroxyl (OH) group. It is one of three hydroxybenzoquinone isomers and one of the simplest hydroxyquinones. The compound is often called 2-hydroxy-1,4-benzoquinone, but the "2-" prefix is superfluous since there is no other hydroxy derivative of 1,4-benzoquinone. The IUPAC name is 2-hydroxycyclohexa-2,5-diene-1,4-dione. It is formed by the reaction of 1,4-benzoquinone with hydrogen peroxide and is a byproduct of the metabolism of phenols, such as 1,2,4-benzenetriol. The enzyme 1,2,4-benzenetriol dehydrogenase catalyzes the conversion of 1,2,4-benzenetriol to 2-hydroxy-1,4-benzoquinone, and the enzyme hydroxybenzoquinone reductase A hydroxybenzoquinone (formula: ) is any of several organic compounds that can be viewed as derivatives of a benzoquinone through replacement of one hydrogen atom (H ...

Molecular Formula
In chemistry, a chemical formula is a way of presenting information about the chemical proportions of atoms that constitute a particular chemical compound or molecule, using chemical element symbols, numbers, and sometimes also other symbols, such as parentheses, dashes, brackets, commas and ''plus'' (+) and ''minus'' (−) signs. These are limited to a single typographic line of symbols, which may include subscripts and superscripts. A chemical formula is not a chemical name, and it contains no words. Although a chemical formula may imply certain simple chemical structures, it is not the same as a full chemical structural formula. Chemical formulae can fully specify the structure of only the simplest of molecules and chemical substances, and are generally more limited in power than chemical names and structural formulae. The simplest types of chemical formulae are called '' empirical formulae'', which use letters and numbers indicating the numerical ''proportions'' of atom ...
