In the title compound, C(15)H(13)N(3)O(4), the pyridine and benzene rings are nearly perpendicular [dihedral angle = 84.24 (5)°]. In the crystal structure, classical O-H⋯N hydrogen bonding between the OH group of the carboxyl unit and a neighbouring pyridine ring N atom and N-H⋯O hydrogen bonding between the imine NH group and a neighbouring O atom of an acyl unit, together with complementary non-classical C-H⋯O hydrogen bonds between carboxyl O atoms and neighbouring CH groups, link the mol-ecu ...[more]
