Fmoc-Met-OSU is widely used in peptide synthesis, particularly in solid-phase peptide synthesis (SPPS). It serves as a protected amino acid derivative, where the Fmoc (fluorenylmethyloxycarbonyl) group protects the amine functionality, allowing selective deprotection during the synthesis process. The active ester (OSU) moiety facilitates efficient coupling with other amino acids or peptide chains, ensuring high yield and purity of the final peptide product. This compound is especially valuable in synthesizing complex peptides and proteins for research in biochemistry, pharmaceuticals, and biotechnology. Its application extends to the development of therapeutic peptides, peptide-based drugs, and studies involving protein-protein interactions.
