Used as an ionic liquid in various industrial and laboratory applications due to its low volatility and high thermal stability. Commonly employed as a solvent in organic synthesis, especially in reactions requiring polar environments, such as Michael additions and Diels-Alder reactions. Also utilized in electrochemistry as an electrolyte component in batteries and supercapacitors because of its good ionic conductivity. Plays a role in biomass processing for the dissolution of cellulose and lignin, aiding in biofuel production. Additionally, explored in extraction processes for separating metals or organic compounds due to its selective solvation properties.
