Used primarily in peptide synthesis, it serves as a building block for creating peptides with specific structural and functional properties. The Fmoc group protects the amino group during the synthesis process, ensuring precise control over peptide chain assembly. It is particularly valuable in solid-phase peptide synthesis (SPPS), where it helps in the production of complex peptides for research and pharmaceutical applications. Its incorporation allows for the study of peptide interactions, enzyme activity, and drug development. The N-methylation enhances stability and can influence the peptide's biological activity, making it useful in designing therapeutic agents.
