Abstract: In the title compound, C13H11Cl2NO2S, the molecule is bent at the S atom with a C-SO2-NH-C torsion angle of -90.4 (2)°. The sulfonyl benzene and the aniline benzene rings are tilted relative to each other by 51.7 (1)°. In the crystal, molecules are linked by N- HO interactions into chains with graph-set notation C(4) along [100].
