The title compound, C16H16BrN3O2, crystallized with two independent molcules in the asymmetric unit. Each molecule has an E conformation about the C=N bond and the dihedral angles between the benzene rings are 30.5 (3) and 28.7 (3)°. In each molecule, there is an O—H⋯N hydrogen bond and the two molecules are linked by an N—H⋯O hydrogen bond. In the crystal, molecules are further linked via N—H⋯O hydrogen bonds into chains propagating along .
