title: 5-Chloro-2-hydroxy-benzene-1,3-dicarb-aldehyde.
abstract: In the crystal structure of the title compound, C(8)H(5)ClO(3), both formyl groups are in the plane of the chloro-phenyl unit and the mol-ecule is stabilized by intra-molecular O-H⋯O hydrogen bonding. The mol-ecules are connected via inter-molecular O-H⋯O hydrogen bonding into chains and are stacked into columns with a centroid-centroid distance between adjacent aromatic rings of 3.914 (2) Å.
