The title molecule, C12H9BrFNO2S, is U-shaped with the central C—S—N—C fragment having a torsion angle of 68.4 (3)° and a dihedral angle between the planes of the two benzene rings of 41.17 (19)°. The crystal structure features strong N—H...O hydrogen bonds between the molecules, forming infinite one-dimensional C(4) chains along [001]. These chains are interconnected via short F...F contacts [F...F = 2.868 (4) Å], forming a one-dimensional ribbon-like architecture.
