Used primarily as an intermediate in organic synthesis, especially in the production of fine chemicals and pharmaceuticals. It serves as a building block for heterocyclic compounds due to its reactive dihydrofuran ring. Commonly employed in cycloaddition reactions, including Diels-Alder reactions, to construct complex cyclic and bicyclic structures. Also utilized in the synthesis of natural products and bioactive molecules. Its ability to act as a diene makes it valuable in creating carbon-carbon bonds in specialized chemical manufacturing. Additionally, it finds use in research settings for developing new catalytic processes and functionalized polymers.
