In the crystal structure of the title compound, C14H14N2O4S, the N-H bond is syn to the ortho-nitro group in the sulfonyl benzene ring and anti to the ortho- and syn to the meta-methyl groups in the aniline ring. The molecule is twisted at the S-N bond with a torsion angle of 71.41 (18)°. The dihedral angle between the planes of the benzene rings is 51.07 (8)°. In the crystal, pairs of N-HOsulfonamide hydrogen bonds link the molecules into inversion dimers.
