Used as a reactive intermediate in organic synthesis, particularly in the production of functionalized polymers and resins. Its vinyl and benzyl chloride groups allow dual reactivity, enabling crosslinking or grafting onto polymer chains. Commonly employed in the development of ion-exchange resins, chromatography supports, and specialty coatings. Also serves as a linker molecule in immobilizing biomolecules or catalysts onto solid supports due to its ability to form stable covalent bonds. Its reactivity makes it valuable in creating custom polymers for pharmaceutical, electronic, and industrial applications.
