In the dynamic field of biochemical research and pharmaceutical development, the precise construction of peptides is paramount. Among the array of specialized reagents, Fmoc-D-Tyr(4-Et)-OH stands out as a critical component for modern peptide synthesis. This article delves into the significance of this Fmoc protected tyrosine derivative, its unique properties, and how it empowers researchers to achieve novel peptide sequences with greater efficiency and stability.

Fmoc-D-Tyr(4-Et)-OH, also known by its chemical name (2R)-3-(4-ethoxyphenyl)-2-(9H-fluoren-9-ylmethoxycarbonylamino)propanoic acid, is a modified form of the amino acid tyrosine. The inclusion of the Fmoc (9-fluorenylmethoxycarbonyl) protecting group is a standard practice in solid-phase peptide synthesis, allowing for controlled deprotection and sequential addition of amino acids. The key differentiator for Fmoc-D-Tyr(4-Et)-OH is the ethoxy modification on the phenol ring of the tyrosine side chain. This modification can influence the solubility, reactivity, and stability of the final peptide, making it a valuable tool for scientists developing peptides with specific therapeutic or diagnostic properties. Understanding the Fmoc-D-Tyr(4-Et)-OH applications in complex synthesis strategies is key for optimizing outcomes.

The primary application of Fmoc-D-Tyr(4-Et)-OH lies in its use as a building block for solid-phase peptide synthesis (SPPS). SPPS is a widely adopted methodology that allows for the automated and efficient assembly of peptide chains. By utilizing Fmoc chemistry, researchers can precisely control the addition of each amino acid, ensuring the formation of the desired peptide sequence. The stability conferred by the ethyl ether linkage on the tyrosine residue can be particularly beneficial, potentially leading to peptides that are more resistant to enzymatic degradation. This enhanced stability is a significant advantage when aiming to buy Fmoc-D-Tyr(4-Et)-OH for applications requiring long-term viability or resistance to harsh physiological conditions.

For laboratories and companies engaged in drug discovery, the availability of high-quality reagents like Fmoc-D-Tyr(4-Et)-OH is essential. The Fmoc-D-Tyr(4-Et)-OH price can vary depending on the purity and supplier, but investing in reliable sources is crucial for reproducible results. When sourcing this compound, it is important to consider the reputation of the Fmoc-D-Tyr(4-Et)-OH suppliers to ensure product integrity and consistency. NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to providing such high-quality chemical intermediates to support groundbreaking research.

Beyond synthesis, this tyrosine derivative plays a role in proteomics studies, where modified amino acids can offer insights into protein function and regulation. The ability to incorporate specifically modified amino acids like Fmoc-D-Tyr(4-Et)-OH into synthetic peptides allows for the creation of model peptides that mimic naturally occurring post-translational modifications, aiding in the study of phosphorylation and other signaling pathways. Exploring the Fmoc-O-ethyl-D-tyrosine usage in these advanced research areas can unlock new avenues of discovery.

In conclusion, Fmoc-D-Tyr(4-Et)-OH is more than just an amino acid derivative; it is an enabler of innovation in peptide science.
