Used in the synthesis of peptides and pharmaceutical intermediates, particularly in the production of chiral compounds. It serves as a key building block in the development of active pharmaceutical ingredients (APIs) due to its ability to introduce specific amino acid structures. Commonly employed in medicinal chemistry for designing drugs with targeted biological activities, such as enzyme inhibitors or receptor modulators. Its protective groups, like the tert-butoxycarbonyl (Boc) group, enable selective reactions during complex organic syntheses.
