Abstract: In the title mol­ecular salt, C12H22N5+·Cl-, the cation is protonated at the dimethyl-substituted tertiary N atom. The piperidine ring adopts a chair conformation with the exocyclic N-C bond in an equatorial orientation. The dihedral angle between the piperidine ring (all atoms) and the pyrimidine ring is 14.00 (1)°. In the crystal, the ions are connected by N-H...N hydrogen bonds, forming inversion dimers, which are further connected by N-H...Cl hydrogen bonds. Aromatic [pi]-[pi] stacking inter­actions [centroid-centroid separation = 3.4790 (9) Å] are also observed in the structure.
