Used as a key intermediate in the synthesis of pharmaceuticals and bioactive compounds, particularly in peptide and medicinal chemistry. The Boc-protected amine and alcohol functional groups allow for selective reactions, making it valuable in multi-step organic syntheses. Commonly employed in the preparation of protease inhibitors, receptor agonists, and other drug candidates where controlled protection and deprotection are required. Also utilized in solid-phase synthesis and as a building block in combinatorial chemistry for generating compound libraries.
