Abstract: The two molecules in the asymmetric unit of the title compound, C13H16O2, form dimers through O-HO hydrogen bonding, resulting in R22(8) rings. Each carboxyl O atom is involved in interamolecular C-HO hydrogen bonds, forming five-membered rings. There exist dissimilar dihedral angles within the two molecules, for example the carboxylate and isopropyl groups make dihedral angles of 59.6 (4) and 71.7 (3)° in the two molecules. There are no intermolecular interactions.
