1-Methyl-3-propylimidazolium Chloride (cas: 79917-89-8) belongs to imidazole derivatives. Many natural products, especially alkaloids, contain the imidazole ring. These imidazoles share the 1,3-C3N2 ring but feature varied substituents. Imidazole is incorporated into many important biological compounds. The most pervasive is the amino acid histidine, which has an imidazole side-chain. Histidine is present in many proteins and enzymes, e.g. by binding metal cofactors, as seen in hemoglobin.Reference of 79917-89-8

Carbohydrates-tailored phase tunable systems composed of ionic liquids and water. [Erratum to document cited in CA153:297068] was written by Chen, Yuhuan;Wang, Yige;Cheng, Qingyan;Liu, Xiaoli;Zhang, Suojiang. And the article was included in Journal of Chemical Thermodynamics in 2010.Reference of 79917-89-8 This article mentions the following:

On page 1056, the first Author’s name should read: Yuhuan Chen. The correct version of the Author line has been corrected On page , in Figure 5, D of phenol in {[C3mim]BF4 + glucose + H2O} system is 2.51, not 13.04. The correct version of Figure 5 is given. In the experiment, the researchers used many compounds, for example, 1-Methyl-3-propylimidazolium Chloride (cas: 79917-89-8Reference of 79917-89-8).
