Used in peptide synthesis as a protected amino acid derivative, particularly in the development of bioactive peptides and pharmaceuticals. The Boc (tert-butoxycarbonyl) group provides temporary protection of the amino function, allowing selective coupling reactions. The 7-aza modification enhances metabolic stability and influences conformational properties, making it valuable in structure-activity relationship (SAR) studies. Commonly applied in research settings for designing enzyme inhibitors, receptor ligands, and probes for biological systems.
