The molecule of the title compound, C19H13Br2N3O2, lies about a twofold rotation axis. The benzene ring makes dihedral angles of 8.9 (2) and 16.4 (2)° with the central pyridine ring and the second benzene ring, respectively. An intramolecular N—HN contact occurs. In the crystal, molecules are connected by pairs of N—HO hydrogen bonds into chains along the c axis.
