Fmoc-Tyr(Me)-OH

Description:

Fmoc-Tyr(Me)-OH, also known as Fmoc-tyrosine methyl ester, is a derivative of the amino acid tyrosine, where the amino group is protected by a fluorenylmethoxycarbonyl (Fmoc) group, and the hydroxyl group of tyrosine is methylated. This compound is commonly used in peptide synthesis as a building block due to its stability and ease of handling. The Fmoc group serves as a protective group that can be removed under basic conditions, allowing for selective deprotection during peptide assembly. The methyl ester enhances the lipophilicity of the tyrosine residue, which can influence the solubility and reactivity of the compound in various chemical environments. Fmoc-Tyr(Me)-OH is typically characterized by its molecular weight, solubility in organic solvents, and its ability to participate in coupling reactions with other amino acids. Its applications extend to the fields of medicinal chemistry and biochemistry, particularly in the synthesis of peptides and proteins for research and therapeutic purposes.
