Used in pharmaceutical synthesis as a protected intermediate for constructing bioactive molecules, particularly in the development of central nervous system agents and receptor modulators. The Boc-protected amine and cyclopropylaminomethyl functional groups enable selective coupling reactions, making it valuable in medicinal chemistry for optimizing drug candidates. Commonly employed in the preparation of protease inhibitors and GPCR-targeted compounds due to its conformational rigidity and favorable pharmacokinetic properties.
