Used primarily as an ionic liquid in electrochemical applications due to its high thermal stability and ionic conductivity. Commonly applied in batteries and capacitors as an electrolyte component. Also serves as a solvent or catalyst support in organic synthesis, especially in reactions requiring non-aqueous polar environments. Its perchlorate anion contributes to oxidative stability, making it suitable for high-voltage systems. Additionally, explored in separation processes for metal ions and in green chemistry initiatives as a reusable reaction medium.
