Assay ≥90% (T)
impurities ≤7.0% water mp 36 °C (Lit. dry VPA) (lit.) density 1.37 g/mL at 20 °C (lit.) SMILES string OP(O)(=O)C=C InChI 1S/C2H5O3P/c1-2-6(3,4)5/h2H,1H2,(H2,3,4,5) InChI key ZTWTYVWXUKTLCP-UHFFFAOYSA-N DESCRIPTION Application Vinylphosphonic acid (VPA) can be used as a monomer unit for the synthesis of poly(vinylphosphonic acid) via free radical polymerization. It is also used to develop copolymers of VPA with acrylonitrile, N-isopropylacrylamide, styrene, vinylpyrrolidone, and acrylic and methacrylic acid. These copolymers find potential application in hydrogels, drug delivery, biomimetic mineralization, and polymer electrolyte membranes in fuel cells.[1] It can also be used as an organic building block to prepare (E)-styryl phosphonic acid derivatives by reacting with various aryl halides via Pd-catalyzed Heck coupling reaction.[2] |
