The title compound, C(15)H(17)ClNO(2)S(+)·C(10)H(15)O(4)S(-)·C(3)H(6)O, was synthesized by N-alkyl-ation of α-amino-(2-chloro-phen-yl)acetate with 2-thienylethyl p-toluene-sulfonate, followed by reaction with (+)-camphor-10-sulfonic acid. In the crystal, the cations and anions are linked through N-H⋯O hydrogen bonds. The thio-phene ring of the cation was found to be disordered over two sites, with refined occupancies of 0.798 (4) and 0.202 (4).
