Used as an ionic liquid in electrochemical applications such as batteries and capacitors due to its high ionic conductivity and thermal stability. Commonly employed as a solvent or electrolyte in fuel cells and dye-sensitized solar cells. Also utilized in organic synthesis and catalysis where a non-aqueous, polar environment is required. Its vinyl group allows for polymerization, making it useful in creating conductive polymeric materials for sensors and electronic devices. Stable under a wide range of conditions, it supports reactions involving sensitive intermediates or air-moisture intolerant reagents.
