In the intricate world of peptide synthesis, the quality and versatility of building blocks are paramount. One such indispensable component is Fmoc-Dap(Alloc)-OH, a protected amino acid derivative that plays a significant role in constructing complex peptide chains. For researchers and B2B procurement managers, understanding the utility and sourcing of this compound is key to successful project outcomes.

Fmoc-Dap(Alloc)-OH, identified by its CAS number 188970-92-5, is a derivative of diaminopropionic acid. The Nα-Fmoc (9-fluorenylmethyloxycarbonyl) protecting group is widely adopted in solid-phase peptide synthesis (SPPS) due to its facile removal under mild basic conditions, typically using piperidine. This allows for sequential addition of amino acids without compromising the growing peptide chain. Concurrently, the Nβ-Alloc (allyloxycarbonyl) group offers orthogonal protection, meaning it can be removed selectively under conditions that do not affect the Fmoc group or other common peptide side-chain protecting groups. This orthogonality is crucial for introducing specific functionalities or modifications at defined positions within the peptide sequence.

The utility of Fmoc-Dap(Alloc)-OH extends to creating peptides with unique structures and applications. Its diaminopropionic acid backbone provides additional points for derivatization or conjugation, which is highly valuable in areas such as drug delivery systems, peptidomimetics, and the development of diagnostic agents. Researchers often seek to buy this compound when they require precise control over amino group protection and deprotection strategies during complex synthesis.

For procurement managers in the pharmaceutical and biotechnology sectors, sourcing reliable Fmoc-Dap(Alloc)-OH is a critical step. Identifying a trusted manufacturer that guarantees high purity and consistent quality is essential. Many companies look for suppliers based in regions known for chemical manufacturing expertise, such as China, where competitive pricing can also be a significant advantage. When searching for this specific amino acid derivative, utilizing its CAS number (188970-92-5) is often the most effective way to find relevant product listings and potential suppliers.

The demand for Fmoc-Dap(Alloc)-OH is driven by the burgeoning fields of peptide therapeutics, diagnostics, and biomaterials. As research progresses into more sophisticated peptide-based molecules, the need for specialized building blocks like this continues to grow. By partnering with reputable chemical suppliers, research institutions and pharmaceutical companies can ensure they have access to the high-quality materials necessary to drive innovation forward. Obtaining a quote from multiple vendors can help secure the best value for bulk purchases, supporting both research-scale experiments and larger production runs.

In summary, Fmoc-Dap(Alloc)-OH (CAS: 188970-92-5) stands as a testament to the advancements in synthetic chemistry, providing researchers with the tools needed for precise peptide construction. For those looking to purchase this vital reagent, focusing on reliable manufacturers and suppliers is key to achieving successful and reproducible results in their peptide synthesis projects.
