Used extensively in peptide synthesis as a building block, particularly in solid-phase peptide synthesis (SPPS). It serves as a protected amino acid derivative, where the Fmoc group safeguards the amino group during the coupling process, while the Boc group protects the side chain of diaminopropionic acid. This compound is crucial for introducing specific functional groups into peptides, enabling the creation of complex peptide structures with precise modifications. Its applications are prominent in drug development, biochemical research, and the production of therapeutic peptides, where controlled and selective protection of amino acids is essential.
