Used as an intermediate in pharmaceutical synthesis, particularly in the development of biologically active compounds. Its structure allows for functionalization at the aldehyde group, making it valuable in constructing nitrogen-containing heterocycles. Commonly employed in medicinal chemistry for building blocks in drug discovery, especially in the synthesis of protease inhibitors and other therapeutic agents. The tert-butyl carbamate (Boc) group provides protection for the amine, enabling selective reactions in multi-step organic syntheses.
