Used as an intermediate in organic synthesis, particularly in the production of pharmaceuticals and fine chemicals. Its cyclic ether structure with an exocyclic double bond makes it valuable for ring-opening and functionalization reactions. Commonly employed in the development of bioactive molecules, including antiviral and anti-inflammatory agents. Also utilized in polymer chemistry as a comonomer to introduce oxygen-containing rings into polymer chains, enhancing flexibility and solubility. Its reactivity allows for easy modification under catalytic conditions, making it suitable for scalable synthetic routes.
