This chemical is primarily used in peptide synthesis as a protected amino acid derivative. It serves as a building block for constructing peptides with specific sequences, particularly when cyclopropyl groups are required in the structure. The fluorenylmethoxycarbonyl (Fmoc) group acts as a protective moiety for the amino group, ensuring selective reactions during peptide chain assembly. Its cyclopropyl side chain contributes to the conformational rigidity of the resulting peptides, which can be crucial for studying protein interactions or designing bioactive compounds. It is commonly employed in solid-phase peptide synthesis (SPPS) for the development of pharmaceuticals, research peptides, and bioconjugates.
