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—H...O hydrogen bond, resulting in a S(7) motif. In the crystal, N—H...O and O—H...O 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 crystal structure of the title compound, C11H15NO4S, two independent mol­ecules are present per asymmetric unit; they are dimerized through O—H...O hydrogen bonds between their carb­oxy groups to generate R22(8) loops. An intra­molecular N—H...O link in one of the mol­ecules closes an S(5) ring. The dimers are linked by N—H...O and C—H...O hydrogen bonds to form a three-dimensional network. The C atoms of the isopropyl group of one of the mol­ecules are disordered over two orientations in a 3:1 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—H...O 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).
