Used as a phase transfer catalyst in organic synthesis, facilitating reactions between reagents in different phases by improving solubility and reactivity. Commonly applied in alkylation, oxidation, and esterification processes. Also serves as a precursor in the preparation of ionic liquids, which are employed as green solvents in catalysis and electrochemistry. Its long alkyl chain enhances lipophilicity, making it effective in membrane-related studies and surfactant formulations. Additionally, it functions as a cationic surfactant with antimicrobial properties, used in disinfectants, cleaning products, and personal care formulations for its ability to disrupt microbial cell membranes and provide antistatic, softening, and dispersing effects in textiles, paints, and cosmetics.
