  • Applications

    3-Vinylpyridine (CAS 1121-55-7) is primarily used as a functional monomer for the synthesis of pyridine-containing polymers, notably ion-exchange resins and metal-chelating plastics. It serves as a precursor for pyridine ligands used in coordination chemistry and catalysis. It is a component in UV-curable coatings and inks, enabling crosslinking and network formation. It also acts as a building block for pyridine-containing fine chemicals, including pharmaceutical and agrochemical intermediates. Additionally, it is used in electronics and sensing applications as part of conductive or responsive polymer systems.
