AM1 and PM3 study of the protonation tautomerization and valence tautomerization of some 4-substituted imidazoles was written by Ogretir, Cemil;Yarligan, Selma. And the article was included in Journal of Molecular Structure: THEOCHEM in 1998.Related Products of 3034-41-1 This article mentions the following:
The gas-phase geometries, relative stabilities, ionization potentials and proton affinities of the different tautomers of some 4-substituted imidazoles and their N-Me derivatives were calculated with full geometry optimization. The predominance of the a (i.e. 1H-form) form with an electron-acceptor group at the 4-position over the b (i.e. 3H-form) form and the predominance of the b (i.e. 3H-form) form with an electron-donor group at the 4-position over the a (i.e. 1H-form) form were confirmed. A correlation between exptl. obtained acidity constants, pKa, and calculated proton affinities was detected. In the experiment, the researchers used many compounds, for example, 1-Methyl-4-nitroimidazole (cas: 3034-41-1Related Products of 3034-41-1).
1-Methyl-4-nitroimidazole (cas: 3034-41-1) 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鈥揅6) is higher than in water and generally decreases with a Imidazole derivatives have antibacterial, antifungal and anticancer functionality. It interacts with DNA and also binds to protein and stops cell division.Related Products of 3034-41-1
