4-Methyl-N-[(2-oxo-1,3-thiazolidin-3-yl)carbonyl]benzenesulfonamide

The asymmetric unit of the title compound, C11H12N2O4S2, contains two independent molecules with similar dihedral angles of 76.7 (1) and 77.3 (1)° between the mean planes of the five- and six-membered rings. In both molecules, the amino groups are involved in intramolecular N—H...O hydrogen bonds. In the crystal structure, weak intermolecular C—H...O hydrogen bonds link molecules into ribbons extended along the a axis.
