Dodecahydroxycyclohexane is an organic compound with molecular formula C₆O₁₂H₁₂ or C₆(OH)₁₂ or (C(OH)₂)₆. It is a sixfold geminal diol with a cyclohexane backbone and can be regarded as a sixfold hydrate of cyclohexanehexone (C₆O₆).

Dihydrate

The dihydrate C₆O₁₂H₁₂·2H₂O can be crystallized from methanol as colorless plates or prisms, that decomposes at about 100 °C.^[1]

Thermal ellipsoid model of the molecular cell of dodecahydroxycyclohexane dihydrate

This compound was synthesized by Joseph Udo Lerch (1816–1892) in 1862^[2] by oxidation of benzenehexol C₆(OH)₆ or tetrahydroxy-p-benzoquinone C₆(OH)₄O₂ and characterized by Rudolf Nietzki and Theodor Benckiser [de] in 1885,^[3] although the product was for a long time assumed to be hexaketocyclohexane with water of crystallization (C₆O₆·8H₂O).

Indeed, this product is still commonly marketed as cyclohexanehexone octahydrate, hexaketocyclohexane octahydrate, triquinoyl octahydrate and similar names. Its true nature was suspected since the 1950s or earlier,^[4] but was confirmed by X-ray diffraction analysis only in 2005.^[5]
