3-[4-(Acetamido)­benzene­sulfonamido]­benzoic acid

In the title compound, C15H14N2O5S, the dihedral angle between the aromatic rings is 63.20 (11) Å. The crystal structure displays classical inter­molecular O—H⋯O hydrogen bonding typical for carb­oxy­lic acids, forming centrosymmetric dimers. These dimers are further connected by N—H⋯O and C—H⋯O hydrogen bonds to form an extended network
