Abstract
The title compound, C7H7ClN2O4S, is of interest as a precursor to biologically active substituted quinolines. Its structure resembles those of the previously reported N-phenylmethane sulfonamide and its 4-nitro, 4-fluoro and 4-bromo derivatives, with slightly different geometric parameters. An intramolecular N—H⋯O hydrogen bond gives rise to a six-membered ring. Intermolecular C—H⋯O contacts stabilize the crystal packing.
