Fmoc-Tyr(4-Et)-OH

Description:
Fmoc-Tyr(4-Et)-OH, also known as 4-Ethyl-L-tyrosine, is a derivative of the amino acid tyrosine, modified with a fluorenylmethyloxycarbonyl (Fmoc) protecting group. This compound is characterized by its aromatic structure, which includes a phenolic hydroxyl group and an ethyl substituent at the para position of the aromatic ring. The Fmoc group serves as a protective moiety for the amino group, facilitating its use in solid-phase peptide synthesis by preventing unwanted reactions during the coupling process. Fmoc-Tyr(4-Et)-OH is typically utilized in the synthesis of peptides and proteins, where it contributes to the overall hydrophobicity and stability of the resulting structures. The presence of the ethyl group enhances the steric bulk and can influence the peptide's conformation and interactions. This compound is soluble in organic solvents, making it suitable for various synthetic applications in peptide chemistry. As with many amino acid derivatives, it is essential to handle Fmoc-Tyr(4-Et)-OH with care, following appropriate safety protocols in a laboratory setting.
