This compound is primarily used in peptide synthesis, particularly in solid-phase peptide synthesis (SPPS). It serves as a protected amino acid derivative, where the fluorenylmethoxycarbonyl (Fmoc) group acts as a protecting group for the amino functionality. This allows for the selective deprotection and elongation of peptide chains during synthesis. The cyclobutyl group in its structure can impart unique conformational properties to the resulting peptides, making it valuable in the design of peptides with specific biological activities or structural features. It is commonly employed in the production of peptide-based drugs, research peptides, and in the study of peptide-protein interactions.
