Used as an ionic liquid solvent in biomass processing, particularly for dissolving cellulose and lignin in the production of biofuels and bioproducts. Its high solvation power enables efficient pretreatment of plant-based materials, enhancing enzymatic hydrolysis and sugar recovery. Also applied in green chemistry as a reusable catalyst medium for organic reactions, offering low volatility and high thermal stability. Employed in electrochemical systems such as batteries and capacitors due to its ionic conductivity. Additionally, serves in CO₂ capture processes and as a reaction medium in polymer synthesis.
