In the crystal structure of the title molecule, C9H8ClNO3, adjacent molecules are arranged into centrosymmetric dimers through pairs of intermolecular O-H...O interactions. Intermolecular N-H...O hydrogen bonds link the dimers into a layer parallel to the bc plane. In the layer, molecules are packed in a face-to-face pi-stacked arrangment, showing pi-pi stacking interactions between the benzene rings with a centroid-centroid distance of 3.6884 (8) A.
