Used in peptide synthesis as a building block, particularly for introducing aminoethylglycine (Aeg) into peptide chains. It is valuable in the development of peptidomimetics and modified peptides for research in drug discovery and biochemical studies. The Fmoc group provides protection during synthesis, ensuring selective reactions and efficient deprotection. Commonly applied in solid-phase peptide synthesis (SPPS) for creating custom peptides with specific structural or functional properties.
