In the title compound, C14H12ClNO3S, the N-H bond is antiperiplanar to the C=O bond. The dihedral angle between the two aromatic rings is 78.7 (1)°. The crystal structure features inversion-related dimers linked by pairs of N-HO(S) hydrogen bonds.
For background to our study of the effect of ring and side-chain substitutions on the crystal structures of N-aryl sulfonamides and for related structures, see: Gowda et al. (2009, 2010a,b).
