This chemical is primarily used in peptide synthesis, particularly in solid-phase peptide synthesis (SPPS). It serves as a building block for introducing alkyne functionalities into peptides, which can be further modified through click chemistry reactions. The Fmoc (fluorenylmethyloxycarbonyl) group acts as a protective group for the amino group, allowing selective deprotection during the synthesis process. Its alkyne moiety enables conjugation with azide-containing molecules, making it valuable in bioconjugation and the development of peptide-based probes, drugs, and biomaterials. Additionally, it is utilized in research involving peptide labeling, imaging, and the study of protein-protein interactions.
