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 for catalytic reactions and CO₂ capture due to its low volatility and tunable properties. Compatible with various organic and inorganic compounds, it serves in electrochemical systems and separation processes.
