Further understanding of the multiple equilibria interaction pattern between ionic liquid and 尾-cyclodextrin was written by Zhang, Jingjing;Shi, Jianfeng;Shen, Xinghai. And the article was included in Journal of Inclusion Phenomena and Macrocyclic Chemistry in 2014.Application of 404001-48-5 This article mentions the following:
The interactions of the ionic liquids 1-alkyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide (CnmimTf2N, n = 2, 4, 6, 8, 10, 12) with 尾-cyclodextrin (尾-CD) in aqueous solutions are investigated in this work. The stoichiometry and apparent association constants are obtained by competitive fluorescence method and isothermal titration calorimetry (ITC). The results show that C2mimTf2N, C4mimTf2N, and C6mimTf2N mainly form 1:1 (guest:host) inclusion complexes with 尾-CD, whereas C8mimTf2N, C10mimTf2N, and C12mimTf2N form both 1:1 and 1:2 inclusion complexes, the latter of which are mainly attributed to the formation of the Cnmim+-2尾-CD complexes. Besides, Tf2N– only forms the 1:1 complex with 尾-CD owing to a charge resonance structure that breaks the symmetry of the structure of Tf2N–, which is proved by Fourier transform IR spectra. The thermodn. parameters obtained by ITC reveal that the formation of the inclusion complexes are enthalpy-controlled for C2mimTf2N, C4mimTf2N, and C6mimTf2N, while for the C8mimTf2N/尾-CD system, the process becomes entropy and enthalpy driven. Based on high-resolution mass spectrometry used with electrospray ionization results, the interaction between CnmimTf2N and 尾-CD is found to follow the multiple equilibrium interaction pattern which was suggested in our previous work. In the experiment, the researchers used many compounds, for example, 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide (cas: 404001-48-5Application of 404001-48-5).
3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide (cas: 404001-48-5) belongs to imidazole derivatives. Imidazole derivatives generally have good solubility in protic solvents. Simple imidazole derivatives, such as 1H-imidazole, 2-methyl-1H-imidazole, and 1,2-dimethylimidazole, have very high solubility in water. Imidazole based anticancer drug find applications in cancer chemotherapy. It is used as buffer component for purification of the histidine tagged recombinant proteins in immobilized metal-affinity chromatography (IMAC).Application of 404001-48-5
