In the title molecular salt, C13H12N3O2+·Cl−, the oxazolyl ring is disordered over two orientations in a 0.536 (15):0.464 (15) ratio, both of which approximate to envelopes with the N atom as the flap in each case. The cation and anion are linked by a charge-assisted N—H...Cl hydrogen bond. In the extended structure, C—H...N, C—H...O and C—H...Cl interactions link the components into a three-dimensional network.
