1-ethyl-2,3-dimethylimidazolium chloride (cas: 92507-97-6) belongs to imidazole derivatives. 1H-imidazole is an imidazole tautomer which has the migrating hydrogen at position 1. It is a conjugate base of an imidazolium cation. It is a conjugate acid of an imidazolide. It is a tautomer of a 4H-imidazole. Imidazole also acts as a microtubule destabilizing agents and inhibits topoisomerase and Cytochrome P450 Family 26 Subfamily A Member 1 (CYP26A1) enzymes.Electric Literature of C7H13ClN2

The melt-phase polymerization of bisphenol A (BPA) and di-Ph carbonate (DPC) catalyzed by alk. metal catalysts produces polycarbonates with high branching, which impairs the product’s properties during weather resistance, ductility, and rheol. The use of an imidazolium-type catalyst can result in a reduced amount of branching relative to the benchmark Cs2CO3 catalyst. Modification of the imidazolium structure, especially by introducing a substitution at the C2 position, definitely improves the catalyst performance in enhancing the catalyst stability and reducing the branching level in the polycarbonate product. For the best catalyst identified (1,3-Ad2-2-Ph-Im-BPA), we have shown that at a DPC/BPA ratio of 1.075 and a catalyst loading of 7 ppm, the specifications can be met at the laboratory scale: polymerization time = 125 min, Mn = 11.0 K, OH = 660 ppm, branching = 460 ppm (鈭?5% reduction relative to the Cs2CO3 benchmark), and yellowness index = 6.3. In the experiment, the researchers used many compounds, for example, 1-ethyl-2,3-dimethylimidazolium chloride (cas: 92507-97-6Electric Literature of C7H13ClN2).
