Used as a phase transfer catalyst in organic synthesis, facilitating reactions between compounds in different phases by enhancing reactivity and selectivity. Commonly applied in esterification, oxidation, and alkylation processes. Also serves as a mild and stable quaternary ammonium salt in formulations for specialty chemicals, including surfactants and emulsifiers. Its hydrophilic nature makes it suitable for aqueous-organic systems, improving yield and reducing reaction time. Additionally, it finds use in electrochemical applications and as a component in some industrial cleaners due to its solubility and low volatility.
