Abstract: In the title compound, C15H16N2O4S, the S atom has a distorted tetrahedral geometry [maximum deviation: O-S-O = 118.25 (7)°]. The two aromatic rings make a dihedral angle of 62.67 (10)° with each other. An intramolecular N-HO hydrogen bond forms an S(6) ring motif. In the crystal, molecules form centrosymmetric dimers via pairwise N-HO interactions, forming an R22(8) ring motif, and these dimers are connected by N-HO hydrogen bonds, generating a three-dimensional network. Furthermore, a weak C-H interaction helps to reinforce the crystal structure. The O atom in the acetamide group is disordered over two positions with major and minor occupancies of 0.52 (5) and 0.48 (5), respectively.
