In the title compound, C15H15NO4S, the dihedral angle between the methyl- and methoxy-substituted benzene rings is 88.99 (12)°. An intramolecular C-HO hydrogen bond occurs. In the crystal, adjacent molecules form inversion-related dimers through strong N-HO hydrogen bonds, generating R22(8) loops. The dimers are further connected through C-HO interactions that form C(8) chains parallel to (001). Molecules are also connected through other C-HO hydrogen bonds along the b axis, forming additional C(8) chains. Two aromatic - stacking interactions [centroid-centroid separations = 3.6150 (1) and 3.6837 (1) Å] generate a three-dimensional architecture.
