The title molecule, C12H18O3, crystallized in the centrosymmetric space group P21/c with two molecules in the asymmetric unit. Each molecule donates three, and accepts three, hydrogen bonds. The OdOa distances in these bonds range from 2.687 (3) to 2.787 (2) Å. The hydroxyl H atoms are ordered. A three-dimensional network of hydrogen-bond chains is formed which is `decorated' with sets of cyclic hydrogen bonds and numerous finite hydrogen-bond patterns. This structure shows both similarities and differences with respect to the structures of the related molecules benzene-1,3,5-triacetic acid and benzene-1,3,5-trimethanol.
