In the intricate world of peptide synthesis, the choice of protected amino acid building blocks significantly impacts the efficiency and purity of the final peptide. Among these essential components, Fmoc-D-Asp(OtBu)-OH, identified by CAS number 112883-39-3, stands out as a particularly versatile and valuable derivative. Its unique structure, featuring the Fmoc (fluorenylmethyloxycarbonyl) protecting group and a tert-butyl ester, makes it an indispensable tool for chemists engaged in both research and commercial peptide production.

The Fmoc group is a cornerstone of modern solid-phase peptide synthesis (SPPS). It offers a base-labile method for N-terminal protection, allowing for selective deprotection under mild conditions without disturbing other sensitive functional groups within the growing peptide chain. This orthogonality is crucial for synthesizing complex peptides, including those with modified amino acids or intricate side-chain protections. Fmoc-D-Asp(OtBu)-OH utilizes this established chemistry to ensure that the aspartic acid residue is incorporated precisely where needed.

The beta-tert-butyl ester modification on the aspartic acid side chain serves multiple critical functions. Firstly, it protects the carboxylic acid group from unwanted reactions during peptide coupling. Secondly, it often enhances the solubility of the amino acid derivative in common organic solvents used in SPPS. Finally, the tert-butyl ester can be cleaved under relatively mild acidic conditions, offering another layer of control in the deprotection strategy. This dual protection system is what makes Fmoc-D-Asp(OtBu)-OH a preferred choice for many synthetic routes.

Researchers and procurement managers constantly seek reliable sources for high-quality peptide synthesis reagents. Understanding the market dynamics, including competitive pricing and consistent availability, is paramount. When you choose to buy Fmoc-D-Asp(OtBu)-OH from a reputable manufacturer, you are investing in the success of your synthesis projects. A trusted supplier will ensure that the product meets stringent purity standards, often exceeding 99%, as verified by analytical techniques like chiral HPLC. This level of quality is non-negotiable for pharmaceutical development and advanced biochemical research.

The applications of peptides are vast and growing, spanning therapeutics, diagnostics, and materials science. As the demand for custom peptides and peptide-based drugs increases, so does the need for robust and efficient synthetic methodologies. Fmoc-D-Asp(OtBu)-OH plays a significant role in enabling the synthesis of a wide array of peptides, including those with therapeutic potential in areas like neuroscience and metabolic disorders. Its availability from manufacturers in China offers a strategic advantage for global supply chains, providing access to cost-effective, high-purity materials.

For procurement managers looking for a consistent supplier of Fmoc-D-Aspartic acid beta-tert-butyl ester, it is essential to partner with manufacturers who prioritize quality control and have a proven track record. The Fmoc-D-Asp(OtBu)-OH price is a factor, but the assurance of product integrity and timely delivery is even more critical. By sourcing CAS 112883-39-3 from a dependable manufacturer, you can streamline your procurement process and focus on your core research and development objectives.
