Used as a cationic surfactant in the synthesis of mesoporous silica nanoparticles, enabling control over particle size and pore structure. Acts as a phase transfer catalyst in organic reactions, facilitating the movement of reactants between immiscible phases. Employed in DNA extraction protocols, where it helps lyse cells and stabilize nucleic acids, especially in plant and microbial samples. Commonly used in the formulation of disinfectants and antimicrobial agents due to its ability to disrupt cell membranes. Also utilized in the preparation of nanomaterials, such as gold nanorods, where it serves as a shape-directing agent.
