<i>N</i>-(4-Sulfamoylphenyl)acetamide

In the title compound, C(8)H(10)N(2)O(3)S, the dihedral angle between the acetamide group and the benzene ring is 15.59 (12)° and the amino group is close to being perpendicular to the benzene ring [N-S-C(ar)-C(ar) (ar = aromatic) torsion angle = 109.4 (2)°]. In the crystal, mol-ecules are linked into supra-molecular tubes parallel to [001] by amine-amide N-H⋯O inter-actions and these are connected into the three-dimensional architecture by amide-sulfonamide N-H⋯O hydrogen bonds. The crystal studied was a racemic twin.
