Abstract
NMR spectra of 1-propylimidazole-4,5-dicarboxylic acid in DMSO- d 6 were studied. It was revealed that it presents in a zwitterion form in solution. The ionization constants in water were determined and their attribution to the certain sites was performed, at that for the deprotonation constants, the correctness of the attribution was confirmed by calculations. Based on the results of calculations, the preferred zwitterion and monoanion forms of 1-propylimidazole-4,5-dicarboxylic acid were selected from several alternative structures.
