In the title compound, C12H13N3O4S, the nitro group is slightly twisted [6.58 (11)°] from the benzene ring plane. The morpholine ring adopts a chair form. In the crystal, intermolecular N—HO hydrogen bonds link the molecules into chains along [110]. There are also π–π contacts [centroid–centroid distance = 3.8301 (11) Å] and C—Hπ interactions to stack neighbouring benzene rings and link the chains into a three-dimensional network. C—HO and C—HS interactions are also observed.
