Fmoc-Tic-OH is widely used in peptide synthesis as a protecting group for amino acids. It is particularly valuable in solid-phase peptide synthesis (SPPS) for constructing complex peptides and proteins. The Fmoc group provides stability during the synthesis process and can be selectively removed under mild basic conditions, ensuring the integrity of the peptide chain. This compound is also employed in the development of peptide-based drugs, where precise control over amino acid sequences is critical. Additionally, it is utilized in research to study peptide interactions, folding, and biological activity, making it a key reagent in biochemistry and pharmaceutical development.
