Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antihypertensive and antiviral agents. Its epoxide ring allows for selective ring-opening reactions, enabling the introduction of functional groups in complex molecule construction. Commonly employed in medicinal chemistry for modifying bioactive molecules due to its stability and reactivity profile. Also utilized in the preparation of specialty polymers where sulfur-containing moieties enhance material properties such as thermal stability and solubility.
