This compound is primarily used in peptide synthesis, particularly in solid-phase peptide synthesis (SPPS). It serves as a building block for incorporating biphenylalanine derivatives into peptides, which are valuable for studying protein-protein interactions and designing peptide-based drugs. The Fmoc (fluorenylmethyloxycarbonyl) group acts as a protecting group for the amine functionality, allowing selective deprotection during the synthesis process. The biphenyl moiety can enhance the stability and binding affinity of peptides, making them useful in developing therapeutic agents or biochemical probes. Additionally, it finds applications in material science for creating functionalized surfaces or polymers with specific properties.
