This compound is primarily used in peptide synthesis as a protected amino acid derivative. It serves as a building block in solid-phase peptide synthesis (SPPS), where the fluorenylmethoxycarbonyl (Fmoc) group acts as a temporary protecting group for the amino functionality. The 4-chlorophenyl moiety provides stability and influences the reactivity of the molecule during peptide chain assembly. Its application is crucial in the production of peptides for pharmaceutical research, drug development, and biochemical studies, enabling the creation of complex peptide structures with high precision.
