This chemical is primarily used in peptide synthesis as a building block. It serves as a protected amino acid derivative, where the fluorenylmethoxycarbonyl (Fmoc) group protects the amine functionality during the peptide chain assembly. This allows for selective deprotection and coupling of amino acids in solid-phase peptide synthesis (SPPS). Its phenyl group provides structural diversity, making it useful in synthesizing peptides with specific properties or biological activities. Additionally, it is employed in the development of pharmaceuticals and bioactive peptides, particularly in research focused on drug discovery and therapeutic agents.
