The asymmetric unit of the title compound, C(12)H(16)BrNO(3)S, contains two independent mol-ecules. In each mol-ecule, the azetidine four-membered ring adopts a nearly planar conformation, the maximum deviations being 0.087 (3) and 0.079 (3) Å. The mean azetidine plane is twisted by 75.2 (2) and 73.6 (2)° with respect to the plane of the benzene ring in the two independent mol-ecules. The crystal packing is stabilized by O-H⋯O hydrogen bonds.
