Used as an ionic liquid in organic synthesis and catalysis due to its excellent solvating properties and thermal stability. Commonly employed as a reaction medium in cross-coupling reactions, such as Heck and Suzuki reactions, where it enhances catalyst efficiency and product yield. Also utilized in electrochemistry as an electrolyte component because of its high ionic conductivity and wide electrochemical window. Its low volatility makes it suitable for green chemistry applications, reducing environmental and health risks compared to traditional volatile solvents. Additionally, it serves as a precursor for generating N-heterocyclic carbenes in organocatalysis.
