2-Vinylpyridine is a colorless to pale-yellow liquid monomer with a strong, unpleasant odor, primarily used in the synthesis of specialty polymers, adhesives, and ion-exchange resins. It is also employed in the production of rubber modifiers and is copolymerized with butadiene and styrene to make vinylpyridine latex for tire-cord adhesives. This chemical has a CAS number of 100-69-6, with a molecular formula of C7H7N and a molecular weight of 105.14. It must be stored at -15 to -20°C and is classified with the signal word "Danger" due to its hazardous properties. Molekula supplies 2-Vinylpyridine from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
