Widely used as a supporting electrolyte in electrochemical applications due to its high solubility in organic solvents and good ionic conductivity. Commonly employed in cyclic voltammetry and other electrochemical studies where a stable and inert electrolyte is required. Also utilized in the synthesis of conductive polymers and in phase-transfer catalysis, facilitating the transfer of anions into organic phases for various organic transformations. Its thermal and electrochemical stability makes it suitable for use in batteries, supercapacitors, and dye-sensitized solar cells. Additionally, it serves as a source of fluoride ions in certain fluorination reactions and is used in analytical chemistry for ion-pairing applications.
