Used as an ionic liquid solvent in biomass processing, particularly for dissolving cellulose and lignin in the production of biofuels and bioproducts. Facilitates efficient extraction and conversion of plant-based materials due to its strong solvating ability and thermal stability. Employed in green chemistry applications as a reusable medium for catalytic reactions and synthesis. Also applied in electrochemistry as an electrolyte component in batteries and sensors due to its high ionic conductivity and low volatility.
