Laviron, Etienne published the artcile< Polarographic and physicochemical studies of nitro, halo-, and carbonyl derivatives of imidazol>, Formula: C4H5BrN2, the main research area is .

The equilibrium between 2 forms of imidazole substituted in position 4 or 5 was investigated. In acidic solutions, the E1/2 values of 4-nitroimidazole (I) and 4-nitro-1-methylimidazole as well as their ultraviolet absorption spectra are identical, indicating that the form A of I predominates over B. The difference in E1/2 between I and 2-nitroimidazole is sufficient for analysis of their mixture The last of the 3 polarographic waves of 2,4,5-triiodoimidazole corresponds to the wave of 2-iodoimidazole, the iodine atom in position 2 being most difficultly reducible. The ratio of the concentrations of form A and B of 4-bromoimidazole is equal to the ratio of the ionization constants of 4-bromo-1-methylimidazole and 5-bromo-1-methylimidazole, viz., 35. Imidazole-4-carboxaldehyde in MeOH or EtOH formed a polarographically inactive hemiacetal.
