Used as an ionic liquid in electrochemical applications due to its good thermal stability and low volatility. Commonly applied in batteries and capacitors as a component of electrolytes, where it enhances ion conductivity and improves device performance. Also utilized as a solvent or catalyst support in organic synthesis, especially in reactions requiring non-aqueous polar environments. Its long alkyl chain contributes to hydrophobicity, making it suitable for biphasic systems and phase-transfer catalysis. Additionally, explored in green chemistry for recyclable reaction media due to its reusability and low vapor pressure.
