The title compound, C(15)H(14)N(2)O(3), was synthesized by the reaction of 4-methoxy-benzaldehyde with 4-hydroxy-benzohydrazide in methanol. The mol-ecule adopts an E configuration about the C=N bond. The two benzene rings make a dihedral angle of 46.6 (2)°. In the crystal structure, mol-ecules are linked into a two-dimensional network parallel to (001) through O-H⋯O and N-H⋯O hydrogen bonds.
