Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of peptide-based drugs. Its protected amine and carboxylic acid functionalities allow for selective coupling reactions, making it valuable in solid-phase peptide synthesis. The compound is also employed in the preparation of enzyme inhibitors and bioactive molecules where stereochemistry plays a critical role in activity. Its Boc-protected amine ensures stability during multi-step syntheses, enabling controlled deprotection and further functionalization.
