Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of biologically active compounds. Its structure allows for the introduction of sulfonamide and amine functionalities, which are common in drug molecules for enhancing binding affinity and solubility. Commonly employed in medicinal chemistry for the preparation of protease inhibitors and other therapeutic agents targeting neurological and inflammatory conditions. Also utilized in the creation of chiral building blocks for asymmetric synthesis, supporting the production of enantiomerically pure drugs.
