The title compound, C9H9ClN2O, is close to planar (r.m.s. deviation for the non-H atoms = 0.0446 Å); it exists in a cis conformation with respect to the C=N double bond. In the crystal, the ketone O atom accepts both N—H⋯O and C—H⋯O hydrogen bonds, which leads to [010] infinite chains incorporating R 2 1(6) loops. The crystal structure also features a C—H⋯π interaction.
