Used as an ionic liquid in electrochemical applications such as batteries and supercapacitors due to its high ionic conductivity and wide electrochemical stability window. Its thermal stability and low volatility make it suitable for high-temperature processes. Commonly employed as a solvent in organic reactions where a polar, non-coordinating medium is required. Also investigated in catalysis and separation processes, especially for CO₂ capture and extraction of biomolecules. Its vinyl and ethyl functional groups allow for polymerization, enabling the formation of conductive polymeric membranes for fuel cells and sensors.
