This chemical is primarily used in peptide synthesis as a protected amino acid derivative. It serves as a building block for constructing peptides, where the fluorenylmethoxycarbonyl (Fmoc) group acts as a protective group for the amino functionality. This allows for selective deprotection during solid-phase peptide synthesis, enabling the stepwise assembly of peptide chains. Its cyclohexyl side chain contributes to the hydrophobicity of the resulting peptide, which can influence the peptide's stability, folding, and interaction with biological targets. It is commonly employed in the development of pharmaceuticals, bioactive peptides, and research applications in biochemistry and molecular biology.
