Benzenehexol

Benzenehexol, also called hexahydroxybenzene, is an organic compound with formula C₆H₆O₆ or C₆(OH)₆. It is a six-fold phenol of benzene. The product is also called hexaphenol, but this name has been used also for other substances.

Benzenehexol is a crystalline solid soluble in hot water, with a melting point above 310°. It can be prepared from inositol (cyclohexanehexol). Oxidation of benzenehexol yields tetrahydroxy-p-benzoquinone (THBQ), rhodizonic acid, and dodecahydroxycyclohexane. Conversely, benzenehexol can be obtained by reduction of sodium THBQ salt with SnCl₂/HCl.
