Used as an ionic liquid in electrochemical applications such as batteries and capacitors due to its good ionic conductivity and wide electrochemical window. Due to its vinyl group, it serves as a monomer in the synthesis of polymeric ionic liquids via electrochemical polymerization, enabling conductive polymers for organic electronics including single-crystal transistors and chemical sensors. It also acts as a solvent and electrolyte component in fuel cells and dye-sensitized solar cells, enhancing device efficiency and stability. Employed in organic synthesis as a catalyst or reaction medium, particularly in reactions requiring polar, anhydrous environments. Its thermal stability and low volatility make it suitable for high-temperature processes. Additionally, it finds use in separation processes and carbon dioxide capture systems.
