The title compound, C9H7NO2S crystallizes with two independent mol-ecules (A and in the asymmetric unit with Z = 8. Both mol-ecules are almost planar with a dihedral angle between the isoxazole and thio-phen rings of 3.67 (2)° in mol-ecule A and 10.00 (1) ° in mol-ecule B. The packing of mol-ecules A and B is of an ABAB⋯ type along the b-axis direction, the configuration about the C=C bond is Z. In the crystal, the presence of C-H⋯O, C-H⋯ N and π-π inter-actions [centroid-centroid distances of 3.701 (2) and 3.766 (2) Å] link the mol-ecu
