title: 3-[4-(Acetamido)-benzene-sulfonamido]-benzoic acid.
abstract: In the title compound, C(15)H(14)N(2)O(5)S, the dihedral angle between the aromatic rings is 63.20 (11) Å. The crystal structure displays classical inter-molecular O-H⋯O hydrogen bonding typical for carb-oxy-lic acids, forming centrosymmetric dimers. These dimers are further connected by N-H⋯O and C-H⋯O hydrogen bonds to form an extended network.
