Used as a protected intermediate in the synthesis of complex organic molecules, particularly in pharmaceuticals and peptide chemistry. The dual protection of amine groups (via Boc and carbamate) allows selective deprotection and stepwise construction of nitrogen-containing compounds. Commonly employed in solid-phase and solution-phase peptide synthesis to prevent unwanted side reactions. Also utilized in the preparation of bioactive molecules such as protease inhibitors and receptor agonists where controlled amine reactivity is essential.
