  • Applications

    Dodecyltriphenylphosphonium bromide (CAS number: 15510-55-1) is a quaternary phosphonium salt with a long alkyl tail and may be used as a cationic surfactant in detergents, cleaners, coatings, and inks; it may also function as a phase-transfer catalyst in organic synthesis to facilitate reactions at aqueous–organic interfaces; it may serve as a precursor or component in specialty ionic liquids and solvent systems for targeted reactions; and it can act as an additive in polymer formulations to modify dispersion, wetting, and surface properties of plastics and coatings.
