Effect of substituents on the electronic structure and spectral characteristics of imidazole derivatives in the ground and excited states was written by Prokop’eva, T. M.;Vysotskii, Yu. B.;Dadali, V. A.;Sokolenko, V. A.. And the article was included in Ukrainskii Khimicheskii Zhurnal (Russian Edition) in 1982.Product Details of 83741-35-9 This article mentions the following:
Ground- and excited-state electron d. distributions were calculated for imidazole, benzimidazole, their protonated and anionic forms, and 1-phenylimidazole by the PMO LCAO SCF method. The results of the calculations corresponded to exptl. reactivity data. The lowest singlet-singlet transition energies were also calculated for benzimidazoles, and these agreed with exptl. spectra. In the experiment, the researchers used many compounds, for example, 4-Bromo-1H-benzoimidazole (cas: 83741-35-9Product Details of 83741-35-9).
4-Bromo-1H-benzoimidazole (cas: 83741-35-9) belongs to imidazole derivatives. The solubility of imidazoles in ethers is lower than that in alcohols and decreases with increasing chain length of the ethers . In contrast, the solubility of benzimidazoles in alcohols (C3–C6) is higher than in water and generally decreases with a Imidazole has been usedin the lysis, wash and elution buffer for the purification of histidine tagged Sonic Hedgehog(shh-N) protein, in elution buffer in stepwise gradient for the purification of histidine tagged aldo keto reductases using nickel affinity chromatography, as a component of homogenization buffer for the purification of phagosomal compartments from dendritic cells.Product Details of 83741-35-9
