چکیده
The title compound, C(15)H(14)N(2)O(4), was prepared from 3,4-dihy-droxy-benzaldehyde and 2-meth-oxy-benzhydrazide in absolute methanol. An intra-molecular N-H⋯O hydrogen bond makes an S(6) ring motif and the dihedral angle between the aromatic rings is 3.2 (3)°. The meta-O atom is disordered over two positions in a 0.809 (6):0.191 (6) ratio. The crystal structure features O-H⋯N and O-H⋯O hydrogen bonds.
