Widely used as a phase transfer catalyst in organic synthesis, enabling efficient anion exchange reactions in non-polar environments. Commonly employed in the preparation of quaternary ammonium salts and in nanomaterial synthesis due to its long hydrophobic chains that promote self-assembly. Frequently utilized in antimicrobial coatings and surface treatments where its cationic nature disrupts microbial cell membranes. Also serves as a stabilizing agent in colloidal systems and in the fabrication of layered organic-inorganic hybrids for advanced functional materials.
