Used in organic synthesis as a protected amine intermediate, particularly in the development of pharmaceuticals and bioactive molecules. Its structure allows for selective functionalization of nitrogen atoms, making it valuable in the construction of complex nitrogen-containing compounds. Commonly employed in medicinal chemistry for peptidomimetics and as a building block in the synthesis of kinase inhibitors and CNS-active agents. The tert-butyl carbamate (Boc) protection ensures stability during multi-step reactions, while the oxalate salt form enhances crystallinity and handling properties.
