Used as a phase-transfer catalyst in organic synthesis, facilitating reactions between compounds in different phases. It is particularly effective in nucleophilic fluorination reactions, where it introduces fluorine atoms into organic molecules. Additionally, it serves as a desilylating agent, removing silyl protecting groups from molecules in a controlled manner. This solution is also employed in the preparation of ionic liquids and as a reagent in the synthesis of pharmaceuticals and fine chemicals. Its ability to stabilize anions makes it valuable in various electrochemical applications.
