Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of protease inhibitors and antiviral agents. Its structure enables selective functionalization in multi-step organic reactions, making it valuable in medicinal chemistry for constructing heterocyclic frameworks. Commonly employed in the preparation of bioactive molecules where sulfonyl and carbonyl functionalities are required for target binding. Also utilized in agrochemical research for designing novel active ingredients with enhanced stability and reactivity.
