Used as a phase transfer catalyst in organic synthesis, facilitating reactions between compounds in different phases by improving solubility and reactivity. Commonly applied in alkylation reactions, esterifications, and nucleophilic substitutions where efficient ion transport is required. Also utilized in the preparation of functionalized polymers and as a modifier in electrochemical systems due to its ionic character and stability. Its polar structure makes it suitable for enhancing reaction rates in nonpolar solvents.
