Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other bioactive molecules. Its structure allows for selective modification, making it valuable in medicinal chemistry for creating drug candidates targeting cancer and inflammatory diseases. The tert-butyl ester group protects the carbamic acid during reactions and can be removed under mild acidic conditions when needed, enabling controlled stepwise synthesis. Commonly employed in research settings for building complex nitrogen-containing heterocycles.
