Abstract: The title compound, C12H11N3O3S, was obtained as a by-product during the attempted preparation of a thiazolone. The dihedral angle between the benzene and the thiazole ring is 85.36 (5)°. The ethanone group is coplanar with the thiazole ring, whereas the nitro group is twisted away from the attached benzene ring by 10.7 (2)°. Intermolecular C-HO and N-HO hydrogen bonds, involving the ethanone O atom, link the molecules into a two-dimensional network parallel to the bc plane.
