  • Applications

    2-Ethenyl-6-methylpyridine (CAS 1122-70-9) is used primarily as a reactive monomer and synthetic intermediate for specialty polymers and resins, such as copolymers with styrene or acrylates for coatings and adhesives. It also serves as a building block in organic synthesis for pharmaceutical and agrochemical applications. The vinyl group on the pyridine framework enables incorporation into polymer systems used for ion-exchange and resin applications. Additionally, it can be a precursor to pyridine-based ligands and chelating agents used in industrial catalytic processes. In some formulations, it is investigated as a reactive component in coatings and inks, subject to local regulations and formulation limits.
