2-Hy­droxy-3,5-diiso­propyl­benzoic acid

The title compound, C13H18O3, crystallizes with three independent mol­ecules in the asymmetric unit. In the crystal structure, two of the mol­ecules form a hydrogen-bonded dimer, while the third forms a centrosymmetric hydrogen-bonded dimer with its symmetry-equivalent mol­ecule. In each independent mol­ecule, there is an intra­molecular O—H⋯O hydrogen bond
