In the title compound, C(10)H(7)NO(2)S(2)·0.5CH(3)OH, the dihedral angle between the aromatic rings is 11.43 (11)° and a short intra-molecular C-H⋯S contact occurs. The methanol solvent mol-ecule is equally disordered over two sets of sites. In the crystal, inversion dimers linked by pairs of N-H⋯O hydrogen bonds occur. The methanol solvent mol-ecule connects the dimers through O-H⋯S and O-H⋯O inter-molecular hydrogen bonds. Further stability is afforded by C-H⋯π and π-π inter-actions [centroid-centroid separation = 3.5948 (13) Å].
