Used primarily as a reactive intermediate in organic synthesis, this compound serves as a versatile monomer in polymer chemistry. Its vinyl and lactone functionalities enable copolymerization with other monomers to produce specialty polymers with tailored properties. These polymers find use in coatings, adhesives, and functional materials where biodegradability or specific reactivity is desired. The compound’s cyclic ester group also allows for post-polymerization modifications, making it valuable in designing biocompatible materials and drug delivery systems. Additionally, it acts as a building block in synthesizing complex molecules for pharmaceuticals and fine chemicals.
