The title molecule, C12H10N2O3S, is nonplanar with an interplanar angle of 33.44 (7)degrees between the benzene and thiophene rings. In the crystal there exist only weak intermolecular C-H center dot center dot center dot O interactions, pi-pi interactions between the benzene rings [centroid-centroid distance = 3.7465 (14) angstrom] and X-Y center dot center dot center dot center dot interactions to the thiophene and benzene rings [N center dot center dot center dot centroid distances = 3.718 (3) and 3.355 (3) angstrom respectively]. Intermolecular C-H center dot center dot center dot O interactions link the molecules into chains parallel to the a axis.
