title: 2-{4-[Acet-yl(eth-yl)amino]-benzene-sulfonamido}-benzoic acid.
abstract: In the title compound, C(17)H(18)N(2)O(5)S, the dihedral angle between the aromatic rings is 68.59 (10)° and the C-S-N-C torsion angle is -81.84 (18)°. The mol-ecular conformation is stabilized by an intra-molecular N-H⋯O hydrogen bond, generating an S(6) ring. In the crystal, mol-ecules are linked by C-H⋯O and O-H⋯O hydrogen bonds into a three-dimensional network.
