2-Hy-droxy-6-isopropyl-3-methyl-benzoic acid.

The title compound, C(11)H(14)O(3), is a multiple-substituted derivative of benzoic acid. Intra-cyclic C-C-C angles span a range of 117.16 (19)-122.32 (19)°. Apart from intra-molecular hydrogen bonds between hydroxyl and carboxyl groups, inter-molecular hydrogen bonds are present in the crystal structure, the latter ones giving rise to centrosymmetric carb-oxy-lic acid dimers.
