In the title compound, C12H10N2O3S, the dihedral angle between the benzene and thiophene rings is 43.17 (4)°. The crystal structure is devoid of any hydrogen-bonding interactions. However, π–π interactions between the benzene and thiophene rings [distance between ring centroids = 3.6850 (11) Å] stack the molecules along the a axis. The absolute structure could not be determined as the crystal studied was a racemic twin with a BASF parameter of 0.31 (6).

The title molecule, C12H10N2O3S, is nonplanar with an interplanar angle of 33.44 (7)° between the benzene and thiophene rings. In the crystal there exist only weak intermolecular C—HO interactions, π–π interactions between the benzene rings [centroid–centroid distance = 3.7465 (14) Å] and X—Yπ interactions to the thiophene and benzene rings [Ncentroid distances = 3.718 (3) and 3.355 (3) Å, respectively]. Intermolecular C—HO interactions link the molecules into chains parallel to the a axis.
