1-Carboxy­methyl-2-ethyl-4-methyl-1H-imidazol-3-ium chloride monohydrate

In the title compound, C8H13N2O2+·Cl−·H2O, the methyl C atom of the ethyl group is slightly out of the imidazole plane, with an N—C(ring)—C—C torsion angle of −15.1 (2)°. In the crystal structure, there are strong inter­molecular hydrogen-bonding inter­actions between the solvent water mol­ecule, the free chloride anion and the organic cation, resulting in a two-dimensional supra­molecular network in the ab plane.
