Used as a precursor in the synthesis of ionic liquids, particularly for creating functionalized imidazolium-based materials with applications in electrochemistry and catalysis. Its vinylic group allows for polymerization, enabling the development of conductive polymeric membranes in fuel cells and batteries. Commonly employed in designing task-specific ionic liquids for use as solvents in organic reactions, where it enhances reaction efficiency and selectivity. Also utilized in sensor technologies due to its ability to form stable, ion-conductive films.
