In the title salt, C(12)H(18)NO(+)·Cl(-), N-H⋯Cl inter-actions between the free chloride anions and the organic cations connect the mol-ecules into hydrogen-bond dimers, forming a R(2) (2)(8) motif. The dimers are linked by C-H⋯O hydrogen bonds into chains extending along [301]. The carbonyl group is co-planar with the phenyl ring [C-C-C=O torsion angle = -3.3 (7)°]. The side chain has an E conformation.
