Used as an ionic liquid in catalytic reactions, particularly in organic synthesis and transition-metal catalysis, due to its excellent solvation properties and thermal stability. It serves as a non-volatile, reusable solvent in cross-coupling reactions such as Heck and Suzuki reactions, enhancing catalyst performance and recyclability. Its low vapor pressure and high ionic conductivity also make it suitable for electrochemical applications, including batteries and sensors. Additionally, it is employed in separation processes and as a reaction medium in green chemistry initiatives where traditional volatile solvents are undesirable.
