Cyclobutanol is an organic compound with the chemical formula C4H8O; it is defined as a cyclobutyl group with a hydroxyl group pendant and thus a cycloalkanol. Physically, it is a yellowish clear liquid[1] that crystallizes orthorhombically at low-temperatures.[2]

Cyclobutylamine's Demjanov rearrangement with nitrous acid gives cyclobutanol,[3] and cyclopropylmethanol rearranges in strong acid to the same.[4] Metal hydrides reduce cyclobutanone to cyclobutanol;[5] conversely, cyclobutanol oxidation is a salt-free route to cyclobutanone.[4]
