Used as a reactive monomer in polymer chemistry, particularly in the synthesis of functional polymers with flame-retardant properties. Its phosphonate group contributes to thermal stability and flame resistance, making it valuable in coatings, adhesives, and textile treatments where fire safety is critical. It can also participate in radical copolymerization with other vinyl monomers to tailor polymer performance. Additionally, it finds use in research for developing novel biomaterials and corrosion-inhibiting films due to the phosphorus functionality.
