The title compound, C(20)H(18)N(2)O(4), is a chalcone derivative of pyrazole. The pyrazole ring is inclined at a dihedral angle of 19.29 (12)° to the methoxy-phenyl ring mean plane, and by 1.19 (13)° to the phenyl ring. The mol-ecular structure is stabilized by an intra-molecular O-H⋯O hydrogen bond, making an almost planar (r.m.s. deviation = 0.0243 Å) six membered ring.
