General description
Imidazole-d4 is a deuterated NMR solvent useful in NMR-based research and analyses. Far-infrared spectrum of imidazole-d4 in the range of 300-33-cm-1 has been investigated.
Application
Imidazole-d4 may be used in the synthesis of 1-ethylimidazole-d8 by reacting with ethyl iodide-d5 and 1-butylimidazole-d12 by reacting with butyl iodide-d9. These compounds form the precursors for the preparation of perdeuterated cellulose solvents, 1-ethyl-3-methylimidazolium acetate (EMIM-OAc-d14) and 1-butyl-3-methylimidazolium acetate (BMIM-OAc-d18).
