Used in peptide synthesis as a building block, it helps in the protection of amino groups during the formation of peptide bonds. Its Fmoc group can be easily removed under mild basic conditions, making it valuable in solid-phase peptide synthesis for producing complex peptides and proteins. Additionally, it serves as a linker in combinatorial chemistry for creating diverse molecular libraries, aiding in drug discovery and development. Its application extends to biochemical research where precise control over peptide sequences is required.
