The asymmetric unit of the title compound, C9H7NO2S, contains two crystallographically independent molecules (AandB). Both molecules are almost planar [maximum deviations = 0.047 (1) and 0.090 (1) Å, respectively, for the S atoms] with the oxazole and thiophene rings being inclined to one another by 2.65 (16)° in moleculeAand by 4.55 (15)° in moleculeB. In the crystal, the individual molecules are linkedviaC—H...O hydrogen bonds, forming –A–B–A–B– chains along the [10-1] direction. The chains are linkedviaC—H...π and π–π interactions [intercentroid distances = 3.767 (2) and 3.867 (2) Å] involving inversion-related oxazole and thiophene rings in both molecules, forming a three-dimensional structure.
