N-Methyl-N-nitroso-p-toluene-sulfon-amide.

The crystal structure of the title compound, C8H10N2O3S, displays predominant C-H⋯O hydrogen-bonding and π-π stacking inter-actions. The hydrogen bonds are between the O atoms of the sulfonyl group and H atoms on methyl groups. The π-π stacking inter-actions occur between adjacent aromatic rings, with a centroid-centroid distance of 3.868 (11) Å. These inter-actions lead to the formation of chains parallel to (101).
