Used primarily in peptide synthesis, this compound serves as a building block for creating specific peptide sequences. It is particularly valuable in solid-phase peptide synthesis (SPPS) due to its Fmoc protecting group, which can be easily removed under mild basic conditions. This allows for the stepwise construction of peptides with high precision. Its application is crucial in the development of pharmaceuticals, bioactive peptides, and research tools for studying protein interactions and functions. The D-configuration of the isoasparagine residue can be employed to enhance the stability or modify the biological activity of synthetic peptides, making it useful in drug discovery and biochemical research.
