(10-Bromodecyl)phosphonic acid is primarily utilized in the field of surface modification and material science. It is often employed as a self-assembled monolayer (SAM) precursor, where it binds to metal oxide surfaces to alter their properties. This chemical is particularly useful in improving the adhesion and compatibility of coatings, films, or other materials on substrates like aluminum, titanium, or stainless steel. Additionally, it finds applications in the development of corrosion-resistant surfaces and in the functionalization of nanoparticles for use in catalysis or biomedical research. Its bromine end-group also allows for further chemical modifications, making it a versatile intermediate in organic synthesis.
