The title compound, C21H16N2O2, was derived from 1-(2-hydroxyphenyl)-3-(4-methoxyphenyl)propane-1,3-dione. The pyrazole ring and one of the hydroxy-substituted benzene rings are approximately coplanar, forming a dihedral angle of 7.5 (3)°. The relative conformation of these rings may be influenced by an intramolecular O—H...N hydrogen bond. In the crystal structure, intermolecular O—H...O hydrogen bonds involving different hydroxy groups of symmetry-related molecules form extended chains along [201].
