In the title compound, C6H10N3+·Cl-, the cation is essentially planar with an r.m.s. deviations of the fitted atoms of 0.008 Å. In the crystal, adjacent ions are linked by weak N-HCl hydrogen bonds involving the pyrimidine and amine N atoms, forming a three-dimensional network. C-H interactions between the methyl and pyrimidine groups and - stacking [centroid-centroid distance = 3.474 (1) Å] between parallel pyrimidine ring systems are also observed.
