In the title compound, C(17)H(17)NO(4), the dihedral angle between the two aromatic rings is 59.64 (5)°. The (meth-oxy-imino)-ethanoic acid fragment is nearly perpendicular to the attached benzene ring [dihedral angle = 81.07 (4)°]. In the crystal, pairs of O-H⋯O hydrogen bonds between carb-oxy groups link mol-ecules into inversion dimers. In addition, π-π stacking inter-actions between inversion-related benzene rings are observed [centroid-centroid distance = 3.702 (1) Å].
