Used primarily as a supporting electrolyte in electrochemical applications due to its high solubility in polar organic solvents and good ionic conductivity. It is commonly employed in batteries, supercapacitors, and fuel cells to facilitate ion transport without participating directly in the redox reactions. Also utilized in organic synthesis as a source of non-coordinating anions, particularly in catalysis and cationic metal complex formation. Its stability under various reaction conditions makes it suitable for use in photochemistry and materials science, including the preparation of conductive polymers and nanomaterials.
