(2R)-2-Benzenesulfonamido-2-phenylethanoic acid

In the title compound, C14H13NO4S, the dihedral angle between the aromatic ring planes is 45.52 (18)°. In the crystal structure, intermolecular N—H⋯O and O—H⋯O hydrogen bonds lead to chains of molecules 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 interactions.
