Used as a key intermediate in the synthesis of specialty polymers and resins, particularly in the production of cross-linking agents for high-performance materials. Its vinyl group enables polymerization reactions, while the chlorine atoms allow for further functionalization through substitution reactions. Commonly employed in the development of heat-resistant and chemically stable coatings, adhesives, and electronic materials. Also utilized in the manufacture of certain agrochemicals and pharmaceuticals where aromatic ring systems with specific substitution patterns are required. Its bifunctional reactivity makes it valuable in organic synthesis for constructing complex molecular architectures.
