In the title compound, C11H13BrN2O2, the dihedral angle between the phenyl ring and the almost planar (r.m.s. deviation = 0.011 Å) C-C(Br)=N-N(H)- fragment is 74.94 (16)°. In the crystal, molecules are linked by N-HO hydrogen bonds, which generate C(6) chains propagating in . Weak aromatic - stacking [centroid-centroid separation = 3.784 (3) Å] may also help to consolidate the packing.
