In the title compound, C12H10N2O3S, the dihedral angle between the benzene and thiophene rings is 43.17 (4)degrees. The crystal structure is devoid of any hydrogen-bonding interactions. However, pi-pi interactions between the benzene and thiophene rings [distance between ring centroids = 3.6850 (11) angstrom] 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).
