Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of bioactive molecules and peptide mimetics. Its protected amine and carboxylic acid functionalities make it valuable in solid-phase and solution-phase peptide synthesis. Commonly employed in medicinal chemistry for constructing constrained ring systems, which can enhance metabolic stability and receptor selectivity in drug candidates. Also utilized in the preparation of cyclobutane-based scaffolds for structure-activity relationship (SAR) studies.
