Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of biologically active molecules and peptide-based drugs. Its structure supports the incorporation of constrained amino acid motifs, which can enhance metabolic stability and receptor selectivity. Commonly employed in medicinal chemistry for constructing novel drug candidates, especially in programs targeting central nervous system disorders and metabolic diseases. The Boc-protected amine and carboxylic acid functionalities allow for straightforward coupling reactions in solid-phase or solution-phase peptide synthesis.
