Abstract
In the title compound, C(14)H(13)NO(4)S, the dihedral angle between the aromatic ring planes is 45.52 (18)degrees. In the crystal structure, intermolecular N-H center dot center dot center dot O and O-H center dot center dot center dot O hydrogen bonds lead to chains of molecules propagating in [100] in which the the ring motifs R(2)(1)(8), R(2)(2)(8) and R(3)(3)(11) are apparent. These polymeric chains are linked through C-H center dot center dot center dot O interactions.
