Abstract
In the title compound, C11H12N2O3, the pyrazole ring system is essentially planar [maximum deviation = 0.002 (2) Å] and forms a dihedral angle of 66.93 (9)° with the benzene ring. In the crystal packing, pairs of intermolecular N—H⋯O and O—H⋯N hydrogen bonds connect neighbouring molecules into dimers, generating R 2 2(10) and R 2 2(8) ring motifs, respectively. The crystal structure is further stabilized by C—H⋯π interactions.

Summary
R factor = 0.058; wR factor = 0.138; data-to-parameter ratio = 17.8. In the title compound, C11H12N2O3, the pyrazole ring system is essentially planar [maximum deviation = 0.002 (2) Å] and forms a dihedral angle of 66.93 (9) with the benzene ring. In the crystal packing, pairs of intermolecular N—H O and O—H N hydrogen bonds connect neighbouring molecules into dimers, generating R22(10) and R22(8) ring motifs, respectively. The crystal structure is further stabilized by C—H interactions.
