Used as a precursor in the synthesis of ionic liquids, particularly those applied in electrochemical systems such as batteries and capacitors due to their thermal stability and ionic conductivity. Also employed as a methylating agent in organic synthesis, facilitating the transfer of methyl groups under mild conditions. Its rigid bicyclic structure makes it useful in catalysis and as a building block in the design of functional materials. Additionally, it finds use in research settings for developing novel quaternary ammonium salts with potential applications in separation processes and as phase-transfer catalysts.
