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  SnCl/ HCl.

Benzenehexol is a starting material for a class of discotic liquid crystals.

Benzenehexol forms an adduct with 2,2'-bipyridine, with 1:2 molecular ratio.
