Abstract

In the title compound, C13H12N2O3, the phenyl ring is nearly planar, with a maximum deviation of 0.012 (1) Angstrom. The pyrazole ring is planar and forms a 48.45 (5)degrees dihedral angle with the phenyl ring. There is an intramolecular O-H...O hydrogen bond between the hydroxy group and the ketone group. The packing is governed by weak C-H...N, O interactions.
