dodecahydroxycyclohexane

Dodecahydroxycyclohexane is an organic compound with molecular formula or or . It is a sixfold geminal diol with a cyclohexane backbone and can be regarded as a sixfold hydrate of cyclohexanehexone ().

==Dihydrate== The dihydrate can be crystallized from methanol as colorless plates or prisms, that decomposes at about 100 °C. 200px|thumb|left|Thermal ellipsoid model of the molecular cell of dodecahydroxycyclohexane dihydrate This compound was synthesized by Joseph Udo Lerch (1816–1892) in 1862 by oxidation of benzenehexol or tetrahydroxy-p-benzoquinone and characterized by Rudolf Nietzki and in 1885, although the product was for a long time assumed to be hexaketocyclohexane with water of crystallization ().
