title: N-(3-Chloro-4-methyl-phen-yl)maleamic acid.
abstract: In the title compound, C(11)H(10)ClNO(3), the dihedral angle between the benzene ring and the amide group is 6.6 (10)° and an intramolecular O-H⋯O hydrogen bond occurs. In the crystal, molecules are linked by N-H⋯O hydrogen bonds, generating C(7) zigzag chains.
