Abstract

The asymmetric unit of the title compound, C14H13NO5S, contains two independent mol­ecules in which the dihedral angles between the aromatic rings are 83.45 (11) and 86.65 (9)°. In the crystal, the independent mol­ecules are connected by N—H⋯O and O—H⋯O hydrogen bonds, forming a double-chain structure along [401]. A weak π–π stacking inter­action with a centroid–centroid distance of 3.7509 (13) Å and C—H⋯O hydrogen bonds are also observed.
