The representative mono- and dialkyl-substituted derivatives of 4-carbamoylimidazolium-5-olate (1) were synthesized unequivocally. On the basis of their spectral data for ultraviolet absorptionspectra in acidic, basic and neutral solutions, we have found some spectral characteristics which make it facile to clarify the position of substituents.
