Used primarily in peptide synthesis, it serves as a building block for creating complex peptide structures. The Fmoc group provides protection for the amine functionality during the synthesis process, ensuring selective reactions. It is particularly valuable in solid-phase peptide synthesis (SPPS), where it helps in the stepwise assembly of peptides. Additionally, it is employed in the development of pharmaceuticals and bioactive compounds, where precise control over molecular structure is critical. Its hydrate form ensures stability and ease of handling in laboratory settings.
