2-Methyl-5-vinylpyridine丨CAS 140-76-1

2-Methyl-5-vinylpyridine is primarily used as a monomer and intermediate in polymer chemistry, specialty chemical synthesis, and materials research. It is commonly applied in the production of functional polymers, copolymers, and resins where pyridine-containing units impart basicity, adhesion, and metal-binding properties. The compound is also used in the synthesis of ion-exchange materials, coatings, adhesives, and surface-modified polymers. In research and industrial settings, it serves as a building block for preparing heterocyclic intermediates, catalysts, and ligands. Additionally, it is employed in studies focused on polymer modification, crosslinking behavior, and the development of advanced materials with tailored chemical and physical properties.

The compound offers several advantages due to its dual functionality combining a vinyl group and a pyridine ring. The vinyl moiety enables efficient polymerization and copolymerization, while the pyridine nitrogen provides coordination ability, chemical reactivity, and pH-responsive behavior. This combination allows the creation of polymers with enhanced adhesion, dispersibility, and interaction with metal ions or acidic species. The compound exhibits good reactivity under standard polymerization conditions and is compatible with a wide range of comonomers and solvents. Its defined structure supports reproducible polymer properties and consistent performance in both laboratory-scale and industrial material applications.
