2-(4-Bromobenzenesulfonamido)benzoic acid

In the title compound, C(13)H(10)BrNO(4)S, the dihedral angle between the benzene rings is 82.75 (15)degrees. An intramolecular N-H center dot center dot center dot O hydrogen bond generates an S(6) ring motif. In the crystal structure, two molecules form an R(2)(2)(8) centrosymmetric dimer through a pair of O-H center dot center dot center dot O hydrogen bonds. Intra- and intermolecular C-H center dot center dot center dot O hydrogen bonds are also observed
