Abstract: In the molecule of the title compound, C₁₅H₁₅ClN₂O₃S, the S atom adopts a distorted tetrahedral coordination geometry with two O atoms, one N atom of the amide group and one C atom of the aromatic ring. An intramolecular O-HN hydrogen bond results in the formation of a planar six-membered ring, which is oriented with respect to the adjacent aromatic ring at a dihedral angle of 3.38 (11)°. Thus, the two rings are nearly coplanar. In the crystal structure, intermolecular N-HO hydrogen bonds link the molecules into centrosymmetric dimers.
