Fmoc-Tyr(Me)-OH is widely used in solid-phase peptide synthesis (SPPS) as a building block for creating peptides. Its Fmoc (9-fluorenylmethoxycarbonyl) protecting group ensures selective deprotection during synthesis, while the methylated tyrosine residue provides stability and specific functionality to the peptide. This compound is particularly valuable in synthesizing peptides for research in biochemistry and pharmaceuticals, where modified tyrosine residues are required to study protein interactions, enzyme activity, or receptor binding. Additionally, it is employed in the development of peptide-based drugs, diagnostics, and biomaterials, where precise control over peptide structure and properties is essential. Its use enhances the efficiency and accuracy of peptide synthesis processes.
