The title compound, C(14)H(12)ClNO(3)·0.25H(2)O, exists in the keto-amine form, and the aromatic rings are oriented at a dihedral angle of 7.24 (7)°. Bifurcated intra-molecular N-H⋯(O,O) hydrogen bonds result in the formation of planar six- and five-membered rings. In the crystal structure, inter-molecular O-H⋯O and C-H⋯O hydrogen bonds link the mol-ecules into chains. π-π contacts between benzene rings [centroid-centroid distance = 3.5065 (9) Å] may further stabilize the structure. There also exists a weak C-H⋯π inter-action.
