In the title compound, C12H8BrClN2O3, the furan ring makes a dihedral angle of 17.2 (2)° with the six-membered ring. An intramolecular O–HN hydrogen bond stabilizes the molecular conformation. In the crystal, N–HO hydrogen bonds connect the molecules into chains running along the c-axis direction. The crystal packing is additionally stabilized by C—HO interactions into a three-dimensional supramolecular architecture.
