In the dynamic world of chemical synthesis, especially for researchers engaged in peptide chemistry, securing a dependable supply of high-quality building blocks is fundamental to experimental success. Fmoc-D-Glu(OtBu)-OH is one such crucial compound, serving as a protected D-glutamic acid derivative vital for solid-phase peptide synthesis (SPPS). Understanding its characteristics and how to source it effectively can significantly impact research outcomes and operational efficiency.

Fmoc-D-Glu(OtBu)-OH, identified by its CAS number 109745-15-5, is a stereoisomerically pure compound essential for constructing specific peptide sequences. The N-terminal Fmoc (9-fluorenylmethyloxycarbonyl) protection strategy is widely adopted in SPPS because it allows for facile, base-catalyzed cleavage, enabling the sequential addition of amino acids without affecting other sensitive functional groups. The tert-butyl ester on the gamma-carboxyl side chain provides necessary protection and enhances solubility, proving beneficial in various organic solvents used in synthesis.

For researchers, the primary concerns when looking to buy Fmoc-D-Glu(OtBu)-OH are purity and consistency. A high purity level, typically ≥98.0%, is essential to ensure that the synthesized peptides are free from contaminants that could interfere with biological assays or therapeutic applications. The D-configuration is also critical for creating peptides with unique structural properties or enhanced stability against enzymatic degradation, as D-amino acids are generally less susceptible to proteases found in biological systems.

When seeking a reliable supplier of peptide synthesis reagents, researchers should look for companies that provide comprehensive documentation, such as Certificates of Analysis (CoA), detailing purity, optical rotation, and other relevant specifications. Furthermore, understanding the Fmoc-D-Glu(OtBu)-OH price is a practical consideration for budget management. Often, sourcing directly from a manufacturer, especially those with robust production capabilities and competitive pricing structures, can lead to significant cost savings without compromising quality. Many leading manufacturers are based in regions like China, offering both quality and cost-effectiveness.

The applications of Fmoc-D-Glu(OtBu)-OH span across various research fields. It is indispensable for synthesizing therapeutic peptides, research peptides for biochemical studies, and complex peptidomimetics. Its unique properties also make it valuable in areas like bioconjugation and the development of diagnostic tools. As research progresses, the demand for reliable sources of these essential building blocks only increases.
