4-Cyanopyridine in Pharmaceuticals
4-Cyanopyridine is an intermediate for the manufacture of pharmaceuticals. The product is well-known for being used in the production of Isoniazid, which is used in the prevention and treatment of tuberculosis.
4-Cyanopyridine is also used as an intermediate for other pharmaceutical solutions such as to produce DMAP, an organic catalyst.
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.
