In the title compound, C15H14N2O4, the dihedral angle between the two benzene rings is 4.1 (2)°. The mol­ecule adopts an E configuration with respect to the C=N bond. There are intra­molecular O—H⋯N and O—H⋯O hydrogen bonds in the mol­ecule. In the crystal structure, mol­ecules are linked through inter­molecular N—H⋯O and O—H⋯O hydrogen bonds, forming chains running along the c axis.
