Used primarily as an intermediate in organic synthesis, this compound serves in the production of specialty chemicals such as pharmaceuticals, agrochemicals, and polymer modifiers. Its reactive alkene and chloride functional groups allow for versatile transformations, including cross-coupling reactions, nucleophilic substitutions, and ring-closing metathesis. It is also employed in the preparation of heterocyclic compounds and functionalized polymers due to its bifunctional reactivity. Handling requires caution due to potential toxicity and reactivity hazards.
