N-Cyclohexyl-4-[(2-nitroanilino)methyl]thiophene-2-sulfonamide

In the title compound, C17H21N3O4S2, an intramolecular N—H...O hydrogen bond involving the proximate amine and nitro groups is observed. In the crystal, intermolecular N—H...O hydrogen bonds involving the amine and SO2 groups occur. One of the notro O atoms is disordered over two conformations with occupancies of 0.578 (12) and 0.422 (12).
