Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of protease inhibitors and other bioactive molecules. Its protected amine functionality allows for selective reactions in multi-step organic syntheses. Commonly employed in the preparation of peptides and peptidomimetics due to the stability and ease of deprotection of the Cbz group. Also utilized in the production of certain antiviral and anticancer agents where functionalized aminoethyl scaffolds are required.
