2-Vinylpyridine

2-Vinylpyridine is the key intermediate in the production of the API, betahistine, an anti-vertigo medicine. 2-Vinylpyridine is a reactive monomer and once polymerized, the nitrogen is less exposed/accessible than its counterpart, 4-Vinylpyridine. It can be copolymerized with many other monomers, in particular cationic monomers, such as acrylamide, acrylates, and also with other vinyl-based monomers (e.g. styrene). The benefit of the addition of a 6-membered heterocyclic moiety is the increased Van der Waals forces which impart better electrostatic forces to the finished polymer, improving adhesion.

2-Vinylpyridine is used as an intermediate in the manufacture of latex for tires. It is primarily used to improve the core adhesion of the belt to the steel wheel. Vinylpyridines have applicability in adhesives and as co-monomers in dispersants for inks and coatings. 2-Vinylpyridine can be copolymerized with many other monomers, in particular for this application cationic monomers and also with other vinyl-based monomers. 2-Vinylpyridine is a key monomer in butadiene-styrene-2VP latex and is used to promote adhesion between vulcanized rubber and reinforcing fabric cords in tires, belts and hoses. 2-Vinylpyridine is also used in other polymer applications and as an intermediate to other chemical compounds.

Vinylpyridines also have broad applicability as demulsifiers for oil and gas and separations technology.
