  • Applications

    Perfluorooctyl bromide (CAS 423-55-2) is primarily used as a reactive precursor in fluorinated materials chemistry. It acts as an intermediate for introducing long perfluorinated chains into polymers and specialty chemicals, enabling the production of fluorinated polymers and surface-modifying agents. It also serves as a building block for fluorinated coatings and inks or adhesives that impart low surface energy and chemical resistance. In biomedical research, it has been explored as a component of perfluorocarbon emulsions for diagnostic imaging and as an oxygen-transport (blood-substitute) concept, with applications limited by formulation and regulatory considerations. Additionally, the bromide functionality enables substitution to access related fluorinated intermediates used in specialty surfactants and coatings.
