The asymmetric unit of the title hydrated salt, C24H35N2O5 (+)·Cl(-)·2H2O, contains one organic cation that has its protonation site at the amine function, one chloride anion and two lattice water mol-ecules. In the crystal, one pair of lattice water mol-ecules and two chloride anions form a four-membered centrosymmetric hydrogen-bond cycle. In addition, O-H⋯O, N-H⋯O and N-H⋯Cl hydrogen bonds involving the N-H groups, the water mol-ecules and the C=O group are observed. As a result, a hydrogen-bonded layer parallel to (100) is formed. The thickness of such a layer corresponds to the length of the a axis [21.977 (3) Å].
