This compound is widely used in peptide synthesis, particularly in solid-phase peptide synthesis (SPPS). It serves as a protected amino acid derivative, where the Fmoc (fluorenylmethyloxycarbonyl) group protects the amino functionality during the synthesis process. The compound is especially valuable for introducing the D-configuration of diaminopropionic acid (Dap) into peptide chains, which is crucial for creating peptides with specific stereochemistry and biological activity. Its application is essential in the development of peptide-based drugs, research tools, and biomaterials, where precise control over peptide structure is required. Additionally, it is used in the study of peptide folding, interactions, and stability, contributing to advancements in biochemistry and medicinal chemistry.
