In the realm of peptide synthesis, precision and reliability are paramount. Fmoc-Val-OSu, identified by its CAS number 130878-68-1, is a high-purity Fmoc-protected amino acid derivative that plays a critical role in constructing complex peptide chains. Researchers frequently seek to buy Fmoc-Val-OSu from reputable suppliers, with many turning to China for its cost-effectiveness and consistent product quality. This reagent is a cornerstone for advancements in various fields, including pharmaceuticals, biotechnology, and fundamental scientific research.

The key advantage of using Fmoc-Val-OSu lies in its dual functionality: the Fmoc protecting group and the N-hydroxysuccinimide (NHS) ester activation. The Fmoc group provides a stable yet easily removable protecting group for the amino terminus, facilitating controlled chain elongation in solid-phase peptide synthesis (SPPS). The NHS ester enhances the reactivity of the valine's carboxyl group, promoting efficient and rapid coupling to the growing peptide chain. This combination ensures high yields and minimizes side reactions, which are crucial for obtaining pure peptide products.

The purity of Fmoc-Val-OSu is a critical factor that directly influences the success of peptide synthesis projects. Suppliers, especially those in China, often provide Fmoc-Val-OSu with a purity level of 99% or higher, verified through rigorous analytical methods such as HPLC. This high degree of purity guarantees that the valine residue is incorporated accurately into the peptide sequence without introducing unwanted contaminants. Researchers are encouraged to always review the Certificate of Analysis (CoA) provided by the manufacturer to confirm product specifications.

The chemical composition of Fmoc-Val-OSu, denoted by the molecular formula C24H24N2O6 and a molecular weight of approximately 436.45 g/mol, defines its identity and reactivity. Understanding these parameters is essential for accurate stoichiometric calculations and successful implementation in synthesis protocols. When considering sourcing options, particularly for bulk requirements, partnering with Chinese manufacturers can offer significant advantages in terms of both price and quantity.

In summary, Fmoc-Val-OSu is an indispensable tool for modern peptide synthesis. Its high purity, efficient coupling capabilities, and the robust nature of the Fmoc protection strategy make it a preferred choice for researchers engaged in developing new therapeutic peptides, exploring protein functions, and advancing the field of proteomics. By selecting a trusted Fmoc-Val-OSu supplier, scientists can confidently achieve their synthesis goals.
