The title compound, C9H8Br2N2O3, is planar (r.m.s. deviation = 0.030 Å) with the exception of the terminal methyl group which lies out of the plane [1.219 (3) Å]. The conformation about the C=N double bond [1.268 (3) Å] is E. An intra­molecular N—H...N hydrogen bond occurs. Linear supra­molecular chains along the b axis mediated by O—H...O hydrogen-bonding inter­actions feature in the crystal structure. These chains are also stabilized by weak C—H...N contacts.
