Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and biologically active compounds. The cyano group allows for further functionalization, such as conversion to carboxylic acids, amines, or tetrazoles, which are common motifs in drug molecules. The tert-butoxycarbonyl (Boc) protecting group stabilizes the amine during reactions and can be easily removed under mild acidic conditions, making this compound valuable in multi-step syntheses, especially in the development of protease inhibitors and other medicinal agents.
