1-Methyl-1H-imidazol-3-ium chloride (cas: 35487-17-3) 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. This ring system is present in important biological building blocks, such as histidine and the related hormone histamine.Computed Properties of C4H7ClN2

Fluorescence Enhancement of Imidazolium Ionic Liquid by Its Confinement on PVC for In Situ Selective Quantification of Hemoglobin was written by Shu, Yang;Han, Lu;Wang, Xiaofeng;Chen, Xuwei;Wang, Jianhua. And the article was included in ACS Applied Materials & Interfaces in 2013.Computed Properties of C4H7ClN2 This article mentions the following:

A hydrophilic ionic liquid (methylimidazolium chloride, NmimCl)-polyvinyl chloride ionomer (NmimCl-PVC) was prepared by immobilizing and confining N-methylimidazole onto PVC chains. The NmimCl-PVC ionomer exhibits a 4-fold enhancement on the fluorescence intensity with respect to that of NmimCl, attributing to the confinement of ionic liquid by the PVC chain. The fluorescence is excitation-dependent with a maximum at λem430 nm when excited at 325 nm. In addition, the fluorescence intensity of NmimCl-PVC ionomer increases remarkably with the loading ratio of N-methylimidazole in the range of 4.3-15.1%. The fluorescence quantum yield and lifetime were derived to be 0.112/7.1 ns for the NmimCl-PVC ionomer and 0.063/8.8 ns for NmimCl. Furthermore, Hb is selectively adsorbed by NmimCl-PVC and causes significant fluorescence quenching of the ionomer via dynamic quenching and energy transfer between NmimCl-PVC and Hb. A solid surface fluorimetric procedure was developed for surface adsorption and preconcentration of Hb followed by in situ detection. A linear dynamic range of 0.3-26.2 μg mg-1 is achieved with a detection limit of 0.1 μg mg-1. Regarding Hb in aqueous solution, the linear range 5-300 μg mL-1 is achieved along with a detection limit of 2 μg mL-1. In the experiment, the researchers used many compounds, for example, 1-Methyl-1H-imidazol-3-ium chloride (cas: 35487-17-3Computed Properties of C4H7ClN2).
