This compound is primarily used in peptide synthesis, particularly in solid-phase peptide synthesis (SPPS) techniques. It serves as a building block for introducing specific amino acid residues into peptides. The Fmoc (fluorenylmethyloxycarbonyl) group acts as a protecting group for the amino functionality, ensuring selective reactions during peptide chain assembly. The naphthyl group provides a hydrophobic character, which can influence the peptide's interaction with biological targets or its structural properties. This chemical is valuable in the development of peptide-based drugs, research tools, and biomaterials, where precise control over peptide sequence and functionality is essential. Its application is common in pharmaceutical research, biochemistry, and material science.
