  • Applications

    2-Ethyl-4-prop-1-en-2-ylpyridine (CAS 142896-08-0) is a specialized organic synthesis building block. In industrial manufacturing, the isopropenyl substituent enables functionalization and copolymerization, making it suitable as a monomer or crosslinkable intermediate for specialty polymers, coatings, and inks. The pyridine ring provides a heteroaromatic platform that can be leveraged as a precursor for dyes, pigments, and functional materials and as a ligand scaffold in catalyst development for pharmaceutical and agrochemical synthesis. It may also be evaluated for fragrance applications as an odorant or fixative in perfumery, though such use would be formulation- and regulation-dependent. Where applicable, handling should comply with local regulations for pyridine derivatives.
