Used as a cationic surfactant in surface coating applications to improve adhesion and surface wetting. Commonly employed in the synthesis of functionalized nanoparticles for drug delivery due to its ability to modify surface charge and enhance cellular uptake. Acts as a phase transfer catalyst in organic reactions, facilitating the interaction between aqueous and organic phases. Applied in the preparation of antimicrobial coatings because of its biocidal properties against bacteria and fungi. Also utilized in electrochemistry as a modifier for electrode surfaces to control electron transfer processes.
