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.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
