In the intricate world of peptide synthesis, the selection of high-quality reagents is paramount to achieving successful and reproducible results. Among these critical building blocks, Boc-Asp(OtBu)-OSu (CAS: 50715-50-9) stands out as a particularly valuable tool for both solid-phase and solution-phase peptide synthesis. As a leading manufacturer and supplier of fine chemicals and pharmaceutical intermediates, we understand the importance of providing researchers and procurement managers with reliable access to such essential materials.

Boc-Asp(OtBu)-OSu, formally known as N-alpha-tert-butoxycarbonyl-L-aspartic acid beta-tert-butyl ester alpha-N-hydroxysuccinimide ester, is designed for precise incorporation of aspartic acid residues into growing peptide chains. Its structure incorporates several key features that enhance its utility. Firstly, the N-alpha-tert-butoxycarbonyl (Boc) group offers robust protection for the alpha-amino terminus, preventing unwanted side reactions during synthesis. Secondly, the beta-tert-butyl ester protects the side-chain carboxyl group of aspartic acid, which can be selectively cleaved under specific conditions. Most importantly, the activation of the alpha-carboxyl group as an N-hydroxysuccinimide (OSu) ester provides a highly reactive species that readily couples with the free amino group of the next amino acid in the sequence. This characteristic is what makes it a preferred reagent when researchers need to buy high-purity peptide building blocks.

The strategic advantage of using an OSu ester derivative like Boc-Asp(OtBu)-OSu lies in its efficient activation. Compared to other activated esters, OSu esters generally offer a good balance of reactivity and stability, leading to faster coupling times and reduced racemization, which are critical factors for obtaining high-quality peptide products. This is particularly relevant when one is looking to buy amino acid derivatives for complex or long peptide sequences where cumulative errors can significantly impact the final yield and purity. Understanding the Boc-Asp(OtBu)-OSu price from reliable suppliers in China can also be a significant consideration for budget-conscious research projects.

For procurement managers and scientists in the pharmaceutical and biotechnology sectors, securing a consistent supply of Boc-Asp(OtBu)-OSu is vital. Whether you are developing novel peptide therapeutics, diagnostic agents, or advanced research tools, the purity and availability of your starting materials directly influence the success of your project.
