Used as an ionic liquid in catalytic reactions, particularly in organic synthesis and transition metal catalysis due to its high thermal stability and low volatility. Commonly employed as a solvent or catalyst support in coupling reactions such as Heck and Suzuki reactions. Also applied in electrochemical processes, including electrodeposition and as an electrolyte component in certain energy storage devices. Its non-aqueous polar nature makes it suitable for dissolving a wide range of organic and inorganic compounds, enhancing reaction efficiency.
