Used as a phase transfer catalyst in organic synthesis, facilitating reactions between reagents in different phases by transferring ions into organic solvents. Commonly applied in nucleophilic substitutions, esterifications, and oxidation reactions where enhanced reactivity and yield are required. Also utilized in analytical chemistry for ion-pairing applications and in some cases as a cationic modifier in electrode processes. Its stability under various reaction conditions makes it suitable for industrial-scale processes requiring efficient catalytic transfer of anions.
