This chemical is primarily used in peptide synthesis, specifically as a building block for creating custom peptides. It is particularly valuable in solid-phase peptide synthesis (SPPS) where the Fmoc (9-fluorenylmethoxycarbonyl) group acts as a protecting group for the amino acid. The Z (benzyloxycarbonyl) group provides additional protection, ensuring selective reactions during the synthesis process. It is commonly employed in research and pharmaceutical development to produce peptides with specific sequences for studying biological processes or developing therapeutic agents. Its stability and compatibility with SPPS make it a reliable choice for synthesizing complex peptides.
