The title compound C(12)H(17)N(3)O(2) (+)·Cl(-) consists of a discrete NITpPyH cation [NITpPy = 2-(4'-pyrid-yl)-4,4,5,5-tetra-methyl-imidazoline-1-oxyl-3-oxide] and a chloride anion. The NITpPy mol-ecule is protonated at the N atom of the pyridyl ring. The anions and cations are connected via N-H⋯Cl hydrogen bonds.
