Fmoc-D-Tyr(Et)-OH

Product Overview

Fmoc-D-Tyr(Et)-OH represents a highly specialized protected amino acid derivative designed for advanced pharmaceutical research and peptide engineering. As a crucial building block in modern organic synthesis, this compound features a 9-fluorenylmethoxycarbonyl (Fmoc) protecting group on the amine functionality and an ethyl ether modification on the phenolic hydroxyl group of the D-tyrosine backbone. This specific configuration ensures exceptional stability during multi-step synthesis protocols while preventing unwanted side reactions at the phenolic position.

Our manufacturing process adheres to strict international quality standards, ensuring that each batch delivers consistent performance for demanding applications. The D-isomer configuration provides unique stereochemical properties required for specific biological activities and structural conformations in therapeutic peptide design. Researchers and production facilities rely on this intermediate for its reliability and high chemical integrity.

Technical Specifications

Industrial Applications

This protected amino acid is primarily utilized in the solid-phase peptide synthesis (SPPS) of complex pharmaceutical intermediates. The ethyl protection on the tyrosine side chain prevents oxidation and alkylation during the coupling process, ensuring the final peptide sequence remains intact. It is extensively used in the development of novel therapeutic agents, diagnostic peptides, and biochemical research tools.

• Synthesis of modified peptide hormones
• Development of enzyme inhibitors
• Construction of peptidomimetics
• Labeling and probing in biological assays

Quality Assurance and Storage

Every production lot undergoes rigorous analytical testing, including HPLC, NMR, and mass spectrometry, to verify identity and purity. We maintain a low loss on drying specification to ensure stability during shipping and storage. To preserve chemical integrity, the product should be stored in a tightly closed container at refrigerated temperatures, protected from light and moisture. We offer flexible packaging options, including standard 25 kg drums or customized solutions based on client requirements.

Our commitment to quality extends beyond the product itself. We provide comprehensive documentation, including Certificates of Analysis (COA), Method of Analysis (MOA), and Safety Data Sheets (SDS) with every shipment. Our global logistics network ensures timely delivery while maintaining cold chain requirements where necessary. Partner with us for reliable supply chain solutions in fine chemical manufacturing.
