In the title salt, C9H8N3O2+·Cl-, the least-squares planes of the imidazolium and benzene rings are almost coplanar, making a dihedral angle of 4.59 (1)°. In the crystal, the chloride anion links the organic molecules through N-HCl hydrogen bonds, forming chains that run diagonally across the bc face, which compliment strong C-HO hydrogen bonds between neighbouring molecules. These chains are connected to adjacent chains through two weak C-HCl interactions, resulting in hydrogen-bonded sheets extending along the b and c axes. The absolute structure of the title compound was determined using a Flack x parameter of 0.00 (6) and a Hooft y parameter of 0.03 (2).
