In the approximately planar molecule of the title compound, C11H8N4O4S, the dihedral angle between the thiophene and benzene rings is 5.73 (10)°. In the crystal structure, bifurcated inter/intramolecular N-H(O,O) hydrogen bonds are present. The intermolecular links lead to inversion dimers containing an R22(12) graph-set motif.
