Abstract
The thiazine ring in the title compound, C14H13N3O4S2, adopts a half-chair conformation. The methyl group at N3 is axial to the thiazine ring due to t he tetrahedral geometry of the N3 atom. The molecules are stabilized by int ramolecular O-H ... O and intermolecular N-H ... O hydrogen bonds.
