In the title compound, C13H8N2O2S, the essentially planar benzothiazole system [maximum deviation = -0.012 (1) Å for the S atom] is oriented at a dihedral angle of 48.3 (1)° with respect to the benzene ring. The nitro group is substantially twisted from the plane of its attached benzene ring [dihedral angle = 52.0 (1)°]. The crystal packing features C-HO hydrogen bonds, which generate C(6) helical chains propagating along . Weak C-H interactions also occur in the crystal.
