This compound is primarily used in peptide synthesis as a building block for constructing complex peptides. Its fluorenylmethoxycarbonyl (Fmoc) protecting group is crucial in solid-phase peptide synthesis, allowing for selective deprotection and subsequent coupling of amino acids. The trifluoromethylphenyl group enhances the compound's stability and can influence the peptide's biological activity, making it valuable in the development of pharmaceuticals, particularly in designing peptide-based drugs targeting specific receptors or enzymes. Additionally, its unique structure can be utilized in research to study peptide interactions and modifications, aiding in the discovery of novel therapeutic agents.
