摘要：

The title compound, C20H18N2O4, is a chalcone derivative of pyrazole. The pyrazole ring is inclined at a dihedral angle of 19.29 (12)degrees to the methoxyphenyl ring mean plane, and by 1.19 (13)degrees to the phenyl ring. The molecular structure is stabilized by an intramolecular O-H center dot center dot center dot O hydrogen bond, making an almost planar (r.m.s. deviation = 0.0243 angstrom) six membered ring.
