Abstract: In the title compound, C14H13NO4S, the dihedral angle between the aromatic ring planes is 45.52 (18)°. In the crystal structure, intermolecular N-HO and O-HO hydrogen bonds lead to chains of molecules propagating in  in which the the ring motifs R21(8), R22(8) and R33(11) are apparent. These polymeric chains are linked through C-HO interactions.
