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, oxidations, and alkylations where efficient ion transport enhances reaction rates and yields. Also utilized in the preparation of quaternary ammonium salts and in electrochemical studies for modifying electrode surfaces. Its long alkyl chains provide lipophilicity, making it effective in non-polar environments.
