2-Methyl-4-(2-methylbenzamido)benzoic acid

In the crystal structure of the title compound, C16H15NO3, intermolecular N—H⋯O hydrogen bonds link the molecules into chains parallel to the b axis and pairs of intermolecular O—H⋯O hydrogen bonds between inversion-related carboxylic acid groups link the molecules into dimers. The dihedral angle between the two benzene rings is 82.4 (2)°.
