Application

(4-Ethenylphenyl)methylphosphonic Acid is widely used as a monomer or crosslinking agent in the synthesis of functional polymers, particularly for ion-exchange membranes and proton-conductive materials. Its phosphonic acid group enables strong metal-surface adhesion, making it valuable for corrosion inhibition coatings and metal-organic frameworks (MOFs). Researchers also employ it as a ligand for transition-metal catalysts in organic transformations. Additionally, it serves as a precursor for modifying surfaces in biosensors and electrochemical devices.
