Used primarily as a reactive intermediate in organic synthesis, this compound serves in the production of specialty polymers and resins due to its ability to undergo polymerization and copolymerization reactions. Its chlorinated aromatic structure and vinyl functionality make it valuable for modifying thermal and mechanical properties of resulting materials. It is also employed in synthesizing fine chemicals, pharmaceuticals, and agrochemicals where a halogenated styrenic backbone is required. Additionally, it acts as a building block in the development of functionalized polymers for use in coatings, adhesives, and electronic materials.
