Used as a highly efficient solvent in biomass processing, particularly in the pretreatment of lignocellulosic materials to separate cellulose, hemicellulose, and lignin. Facilitates the dissolution of cellulose, enabling easier conversion into biofuels and value-added chemicals. Applied in CO₂ capture systems due to its strong affinity for acidic gases, offering potential in carbon capture technologies. Serves as a reaction medium in organic synthesis, including polymerization and catalytic reactions, benefiting from its low volatility and high thermal stability. Explored in electrochemical applications such as batteries and fuel cells where ionic conductivity and stability are critical.
