Used as a key intermediate in the synthesis of pharmaceutical peptides, particularly in the production of protease inhibitors and antiviral drugs. Its protected amino groups allow for selective coupling in solid-phase peptide synthesis, ensuring high purity and yield. Commonly employed in the development of glycine-based dipeptide mimetics, it supports the creation of biologically active compounds with improved metabolic stability. Also utilized in research settings for labeling and conjugation strategies due to its reactive amine functionality after deprotection.
