Used as an intermediate in organic synthesis, particularly in the preparation of cyclic compounds and functionalized polymers. Its strained cyclooctene ring enables ring-opening metathesis polymerization (ROMP), making it valuable in polymer chemistry for creating tailored macromolecules with specific architectures. The carboxylic acid and ether functionalities allow further chemical modifications, useful in pharmaceutical research for building complex molecular frameworks. Also employed in conjugation strategies involving biomolecules or drug delivery systems where controlled reactivity and biocompatibility are required.
