4-(4-Methylbenzenesulfonamido)benzoic acidN,N-dimethylformamide monosolvate

In the title compound, C14H13NO4S·C3H7NO, the C—S—N—C torsion angle of −64.55 (17)° defines the folded conformation of the molecule. The dihedral angle between the benzene rings is 83.367 (6)°. In a crystal, molecules are linked into a chain along a axis through intermolecular N—H...O and O—H...O hydrogen bonds. There is also an intramolecular C—H...π interaction.
