Used primarily as an intermediate in organic synthesis, this compound serves in the preparation of more complex molecules through its reactive alkene and iodide functionalities. The terminal double bond allows for addition reactions such as hydrohalogenation or epoxidation, while the iodine atom, as a good leaving group, enables formation of Grignard reagents or participation in coupling reactions like Suzuki, Heck, or Negishi couplings, making it valuable in pharmaceutical and agrochemical synthesis. It is also employed in the production of polymers and functionalized long-chain compounds due to its bifunctional nature. Its volatility and reactivity require careful handling in controlled environments.
