2-(Methyl-sulfin-yl)benzamide.

In the crystal of the title compound, C(8)H(9)NO(2)S, synthesized by the oxidation of 2-(methyl-sulfan-yl)benzamide using NaOCl with 2,2,6,6-tetra-methyl-piperidyl-1-oxy (TEMPO) as the catalyst, mol-ecules are linked via inter-molecular N-H⋯O(amide) hydrogen bonds, forming centrosymmetric amide-amide dimers which are extended into a two-dimensional lamellar framework parallel to (100) through amide-sulfinyl N-H⋯O hydrogen bonds. The benzene ring forms a dihedral angle of 25.6†(2)° with the amide group.
