Used primarily as an intermediate in the synthesis of pharmaceuticals, particularly in the development of active ingredients for central nervous system (CNS) drugs. Its structure allows for ring-opening reactions that are valuable in creating chiral molecules with high enantioselectivity. Commonly employed in the preparation of fluorinated analogs in medicinal chemistry, where the fluorine atoms enhance metabolic stability and bioavailability. Also utilized in the production of specialty polymers and agrochemicals due to its reactivity and functional versatility.
