N-(2-Formylphenyl)benzenesulfonamide

In the title compound, C13H11NO3S, the two aromatic rings are oriented at an angle of 88.18 (8)°. Intramolecular N—H...O and C—H...O hydrogen bonds are observed, each of which generates an S(6) ring motif. In the crystal, molecules are linked into C(7) chains along [010] by intermolecular C—H...O hydrogen bonds. The structure is further stabilized by intermolecular C—H...π interactions involving the sulfonyl-bound phenyl ring.
