Decahydroxycyclopentane is an organic compound with formula Шаблон:Chem2 or Шаблон:Chem2. It is a fivefold geminal diol on a cyclopentane backbone.
The compound can be regarded as the fivefold hydrate of cyclopentanepentone. Indeed, the product referred to in the literature and trade as "cyclopentanepentone pentahydrate" (Шаблон:Chem2) is now believed to be the decahydroxycyclopentane.[1][2]
The compound was synthesized by Heinrich Will in 1861, although for a long time it was believed to be a hydrate of Шаблон:Chem2. It can be prepared by oxidation of croconic acid Шаблон:Chem2 with nitric acid.[3] It can be isolated as water-soluble colorless crystals that melt with dehydration at about 115 °C, and slowly decompose at about 160 °C.[4]
