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