Used as an ionic liquid precursor in catalysis and organic synthesis, particularly in palladium-catalyzed cross-coupling reactions due to its ability to stabilize metal catalysts. Its vinyl and allyl functional groups allow for polymerization, making it useful in the development of functionalized poly(ionic liquid)s for electrochemical applications such as batteries and fuel cells. Also employed as a task-specific solvent and electrolyte component owing to its thermal stability and ionic conductivity.
