Application

This Fmoc-protected amino acid derivative is primarily used in peptide chemistry for the synthesis of modified peptides with tailored properties. It serves as a key building block in SPPS (Solid-Phase Peptide Synthesis) due to its orthogonal protecting groups, enabling selective deprotection strategies. Researchers utilize it to introduce sterically hindered or hydrophobic segments into peptide sequences, particularly in drug discovery and bioconjugate development. Its structural features make it valuable for creating peptide-based probes or linkers in bioconjugation workflows.
