This compound is widely used in peptide synthesis, particularly in solid-phase peptide synthesis (SPPS) methods. It serves as a protecting group for amino acids, ensuring selective reactions during the assembly of peptide chains. The Fmoc group can be easily removed under mild basic conditions, making it highly suitable for synthesizing complex peptides without disrupting other functional groups. Its application extends to the production of pharmaceuticals, bioactive peptides, and research compounds, where precise control over peptide structure is essential. Additionally, it is utilized in the development of peptide-based drugs, diagnostics, and biomaterials due to its stability and compatibility with various synthetic protocols.
