This imidazolium-based ionic liquid features a butylsulfonic substituent and a methyl group at the imidazolium core, paired with a hydrogen sulfate anion. It combines high thermal stability with strong solvating power, enabling efficient dissolution of polar and ionic species under standard conditions. The sulfonic acid moiety enhances proton transfer capability, supporting catalytic applications in organic synthesis and electrochemical systems.
1-Butylsulfonic-3-methylimidazolium hydrogensulfate serves as a robust, bench-stable ionic liquid catalyst and reaction medium, enabling efficient acid-catalyzed transformations such as esterifications, acetalizations, and Friedel-Crafts reactions. Its sulfonic acid functionality enhances proton transfer efficiency, while the imidazolium core provides excellent solubility for polar and nonpolar substrates. The hydrogensulfate counterion ensures high thermal stability and facilitates easy product separation, making it ideal for scalable synthesis workflows.
