In the title compound, C(12)H(15)ClNO(+)·C(4)H(5)O(6) (-), the cyclo-hexa-none ring adopts a chair conformation. The benzene ring is significantly twisted so that it is in an almost perpendicular position to the C-N bond with a C(Ar)-C(Ar)-C-N torsion angle of -96.5 (5)°. Intermolecular N-H⋯O and O-H⋯O hydrogen bonds are observed in the crystal structure.
