Abstract: In the title compound, C13H9NO4, the two carboxylic groups and the benzene ring are approximately co-planar with a maximum atomic deviation 0.175 (4) Å, while the pyridine ring is oriented at a dihedral angle of 31.07 (18)° with respect to the benzene ring. In the crystal, molecules are linked by O-HO, O-HN and weak C-HO hydrogen bonds, forming a three-dimensional supramolecular framework.
