The molecule of the title compound, C8H8BrN3OS, is close to being planar, with maximum deviations of -0.127 (3) and 0.135 (5) Å for the N atoms of the -NH- and NH2- groups, respectively. Intramolecular N-HN and O-HN hydrogen bonds to the same acceptor N atom generate S(5) and S(6) ring motifs. In the crystal structure, molecules are connected into  chains by pairs of N-HS hydrogen bonds with R22(8) graph-set motifs. The crystal used for data collection was found to be an inversion twin.
