In the title compound, C(15)H(13)NO(4), the dihedral angle between the substituted benzene rings is 9.9 (8)°. Part of the mol-ecule (the salicylaldimine segment) is disordered over two sets of sites, with a refined site-occupancy ratio of 0.550 (14):0.450 (14). Intra-molecular O-H⋯N hydrogen bonds form S(6) ring motifs. In the crystal, pairs of O-H⋯O hydrogen bonds link mol-ecules into centrosy...
