In the realm of custom peptide synthesis, precision and reliability are paramount. Fmoc-D-Glu(OtBu)-OH, bearing the CAS number 104091-08-9, is a highly specialized building block that enables chemists to create peptides with unique sequences and properties. As a dedicated manufacturer and supplier, NINGBO INNO PHARMCHEM CO.,LTD. understands the critical role this compound plays in advancing scientific discovery.

The D-configuration of the glutamic acid in Fmoc-D-Glu(OtBu)-OH is particularly significant for custom peptide synthesis. It allows for the incorporation of non-natural amino acids into peptide chains, which can enhance stability against enzymatic degradation, modify pharmacokinetic properties, or introduce novel binding affinities. The Fmoc protecting group on the alpha-amine ensures straightforward and orthogonal coupling to the growing peptide chain during solid-phase synthesis. For researchers looking to buy this specific enantiomer, ensuring its correct stereochemistry is as important as its purity.

The tert-butyl ester protection on the gamma-carboxyl is another key feature that facilitates its use in demanding synthetic protocols. This ester is stable under the basic conditions used for Fmoc removal but can be readily cleaved using acidic reagents like trifluoroacetic acid (TFA) during the final resin cleavage step. This differential lability allows for precise control over deprotection and coupling cycles. When engaging with a supplier, inquire about the typical yields and purity achieved when using their Fmoc-D-Glu(OtBu)-OH in SPPS.

The demand for custom peptides is burgeoning, driven by applications in therapeutics, diagnostics, and materials science. Consequently, the reliable sourcing of critical reagents like Fmoc-D-Glu(OtBu)-OH from reputable manufacturers in China and globally is essential. Understanding the factors that influence the price, such as purity levels and order volume, will help procurement managers make strategic purchasing decisions.
