Used as an intermediate in organic synthesis, particularly in the pharmaceutical industry for constructing complex molecules. The cyano group allows for further functionalization, such as conversion to carboxylic acids or amines, enabling the development of active pharmaceutical ingredients. The tert-butyloxycarbonyl (Boc) protecting group stabilizes the amine during reactions and can be easily removed under mild acidic conditions, making it valuable in multi-step synthesis. Commonly employed in the preparation of drug candidates targeting neurological and inflammatory conditions.
