title: N-(3,4-Dimethyl-phen-yl)succinamic acid.
abstract: The asymmetric unit of the title compound, C(12)H(15)NO(3), contains two independent mol-ecules. In both mol-ecules, the conformations of the amide oxygen and the carbonyl O atom of the acid segment are anti to the adjacent CH(2) groups. In the crystal, both molecules form inversion dimers linked by pairs of O-H⋯O hydrogen bonds and N-H⋯O interactions link the dimers into [100] chains.
