4-Acetyl-5-methyl-1-phenyl-1H-pyrazole-3-carboxyl­ic acid

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—H⋯O hydrogen bond between the hydroxy group and the ketone group. The packing is governed by weak C—H⋯N,O interactions.
