[5] Benzenehexol is a crystalline solid soluble in hot water,[4] with a melting point above 310°.

[citation needed] Oxidation of benzenehexol yields tetrahydroxy-p-benzoquinone (THBQ), rhodizonic acid, and dodecahydroxycyclohexane.

[8] Like most phenols, benzenehexol can lose the six H+ ions from the hydroxyl groups, yielding the hexaanion C6O6−6.

[9] The nature of K6C6O6 was clarified[10] by Rudolf Nietzki and Theodor Benckiser [de] in 1885, who found that its hydrolysis yielded benzenehexol.

[11][12] The lithium salt of this anion, Li6C6O6 has been considered for electric battery applications.
