Useful:

• Chemical Classes: Nitrogen Compounds -> Pyridines
• Canonical SMILES: C=CC1=CC=NC=C1
• Uses: 4-Vinylpyridine acts as a co-monomer in styrene-butadiene polymers to promote adhesion between the rubber compound and supporting fibers (or cords) in tires, belts and hoses. It serves as an intermediate for manufacturing chemicals and pharmaceuticals. Further, it is used as a reagent for the modification of cysteine. In addition to this, it is used to make poly(4-vinylpyridine) and elastomers.
