Used primarily as an intermediate in peptide synthesis, especially in the preparation of biologically active compounds and pharmaceuticals. Its structure allows for selective protection of amino groups, making it valuable in solid-phase peptide synthesis. Commonly employed in the development of enzyme inhibitors and receptor agonists/antagonists due to its ability to mimic natural amino acid building blocks. Also utilized in medicinal chemistry for constructing heterocyclic frameworks in drug design, particularly in oncology and neuropharmacology research.
