Used as an ionic liquid precursor in catalysis, particularly in organic synthesis and polymerization reactions. Its vinyl and benzyl functional groups enable cross-linking, making it suitable for creating supported ionic liquid phases in heterogeneous catalysts. Commonly applied in electrochemical systems, such as electrolytes for batteries and fuel cells, due to its good ionic conductivity and thermal stability. Also employed in the preparation of functionalized membranes for separation processes and sensors. Its quaternary ammonium structure enhances solubility and compatibility with various solvents and materials, broadening its use in material science and green chemistry applications.
