Abstract: In the title compound, C13H12N2O4S, the dihedral angle between the benzene rings is 53.44 (14)°. The amide H atom exhibits bifurcated hydrogen bonding: an intramolecular N-H...O hydrogen bond generates an S(7) motif while in the crystal, N-H...O(S) hydrogen bonds link the molecules into zigzag C(4) chains along the c axis.
