Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of active pharmaceutical ingredients (APIs) requiring protected amine functionalities. Its structure allows for selective functionalization in multi-step organic reactions, making it valuable in medicinal chemistry for constructing complex molecules. Commonly employed in the preparation of kinase inhibitors and other bioactive agents where controlled amine reactivity is essential. The tert-butyl ester group enables easy deprotection under mild acidic conditions, facilitating downstream processing in drug synthesis.
