title: 4-[(E)-(5-Bromo-2-hydroxy-phen-yl)methyl-ideneamino]benzene-sulfonamide.
abstract: In the title compound, C(13)H(11)ClN(2)O(3)S, the dihedral angle between the benzene rings is 12.26 (33)° and an intra-molecular O-H⋯N hydrogen bond helps to establish the conformation. In the crystal, N-H⋯O and C-H⋯O inter-actions link the mol-ecules.
