Abstract: In the title compound, C15H15NO4S, the dihedral angle between the benzene rings is 88.87 (1)°. In the crystal, adjacent molecules form inversion dimers through pairs of strong N-HO hydrogen bonds, generating R22(8) loops. Two C-H interactions and an aromatic - interaction [centroid-centroid separation = 3.8191 (1) Å] are also observed.
