Abstract

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.
