Used as a catalyst in organic synthesis, particularly in Friedel-Crafts reactions, due to its ability to enhance reaction efficiency and selectivity. It is also employed in electrochemical applications, such as in the development of batteries, sensors, fuel cells, and electrolysis processes, because of its ionic conductivity, thermal stability, and overall stability. Additionally, it serves as a solvent or co-solvent in various chemical processes, including extraction and separation techniques, owing to its unique solvation properties. In materials science, it is utilized for the synthesis of nanoparticles and other advanced materials, where it acts as a stabilizing or templating agent. Its role in green chemistry is notable, as it can reduce the need for volatile organic solvents and hazardous chemicals, contributing to more sustainable industrial practices with less waste.
