Abstract: In title compound, C14H12N2O5S, the dihedral angle between the sulfonyl benzene ring and the -SO2-NH-C-O segment is 81.5 (2)° and that between the sulfonyl and the benzoyl benzene rings is 89.8 (1)°. In the crystal, molecules are linked into chains along the b axis via intermolecular N-HO hydrogen bonds. C-HO interactions are also observed.
