Fmoc-L-Methionine丨CAS 71989-28-1

Fmoc-L-Methionine is a protected amino acid widely used in peptide synthesis and protein engineering. Its Fmoc (9-fluorenylmethyloxycarbonyl) protective group enables selective and stepwise assembly of peptides using solid-phase peptide synthesis (SPPS), making it essential for the construction of complex peptide sequences. It is particularly employed in the production of therapeutic peptides, peptide-based vaccines, and bioactive compounds in pharmaceutical research. Additionally, Fmoc-L-Methionine is utilized in biochemical and structural studies to investigate protein folding, enzyme mechanisms, and receptor-ligand interactions. Its compatibility with automated peptide synthesizers and high efficiency in protecting the amino group make it a preferred reagent in both laboratory-scale research and commercial peptide manufacturing.

The key benefits of Fmoc-L-Methionine stem from its protective functionality and chemical stability. The Fmoc group allows for controlled, selective deprotection under mild conditions, minimizing side reactions and preserving the integrity of sensitive peptide sequences. Methionine itself introduces a sulfur-containing residue into peptides, which can contribute to structural stability, redox activity, and biological functionality. Fmoc-L-Methionine improves synthetic efficiency by enabling high-purity peptide assembly and is compatible with a wide range of coupling reagents and solvents used in SPPS. Its use supports reproducible peptide synthesis, reduces purification requirements, and facilitates large-scale production of peptides for pharmaceutical, diagnostic, and research applications.
