In the title compound, C12H16N2O6S, the S atom adopts a distorted tetrahedral geometry with an O—S—O angle of 119.76 (13)°. The nitro group is twisted by 35.34 (2)° with respect to the aromatic ring; it accepts an N—HO hydrogen bond, resulting in a S(7) motif. In the crystal, N—HO and O—HO hydrogen bonds connect the molecules into an infinite chain along the a axis. The methyl C atoms of the isopropyl group are disordered in a 1:1 ratio.

In the title compound, C14H21NO4S, the O—S—O angle is 120.06 (11)°, with the S atom adopting a distorted tetrahedral geometry. In the crystal, N—HO hydrogen bonds connect the molecules along the a axis, generating an infinite chain. The disordered C atoms of the isobutyl group were refined with the C—C distances restrained to 1.52 (1) Å and the occupancy ratio refined to 0.504 (3):0.496 (3).
