Used as an ionic liquid in catalysis and organic synthesis due to its high thermal stability and low volatility. Commonly employed as a solvent or catalyst support in coupling reactions, esterification, and biodiesel production. Its long alkyl chain enhances solubility of non-polar compounds, making it suitable for biphasic reaction systems. Also investigated for use in electrochemical applications such as batteries and sensors due to its good ionic conductivity. Shows antimicrobial properties, which can be leveraged in biocidal coatings and disinfectants.
