Used primarily as a key intermediate in organic synthesis, especially in the preparation of bioactive molecules and pharmaceuticals. Its azide group enables click chemistry reactions, making it valuable in drug discovery and bioconjugation processes. Commonly employed in the development of proteolysis-targeting chimeras (PROTACs) and other targeted protein degraders due to its ability to link targeting ligands with effector molecules. Also utilized in polymer science and materials research where controlled functionalization is required. The tert-butyl carbamate (Boc) group provides amine protection during multi-step syntheses, allowing selective deprotection under mild acidic conditions.
