title: (2R)-2-Benzene-sulfonamido-2-phenyl-ethanoic acid.
abstract: In the title compound, C(14)H(13)NO(4)S, the dihedral angle between the aromatic ring planes is 45.52 (18)°. In the crystal structure, inter-molecular N-H⋯O and O-H⋯O hydrogen bonds lead to chains of mol-ecules propagating in [100] in which the the ring motifs R(2) (1)(8), R(2) (2)(8) and R(3) (3)(11) are apparent. These polymeric chains are linked through C-H⋯O inter-actions.
