For chemists and procurement specialists involved in peptide synthesis, securing a consistent and high-quality supply of Fmoc-Asp-OAll (CAS 144120-53-6) is crucial. This protected amino acid derivative, scientifically known as N-alpha-Fmoc-L-Aspartic Acid Alpha-Allyl Ester, plays a pivotal role in constructing complex peptide sequences through solid-phase peptide synthesis (SPPS). This guide aims to provide insights for those looking to buy this vital intermediate, with a focus on the advantages offered by Chinese manufacturers and suppliers.

The strategic use of Fmoc-Asp-OAll in Fmoc SPPS allows for precise control over peptide chain elongation. The Fmoc group on the alpha-amino terminus is readily removed by mild bases, while the allyl ester protecting the beta-carboxyl group provides a means for selective deprotection, often via palladium-catalyzed reactions. This orthogonal protection strategy is invaluable when synthesizing peptides with aspartic acid residues that require specific side-chain modifications or when employing other acid-sensitive protecting groups elsewhere in the molecule. As a white powder, it is easy to handle and store under recommended conditions (2-8°C), maintaining its chemical integrity for demanding applications.

When you need to buy Fmoc-Asp-OAll, it is imperative to source from manufacturers and suppliers who guarantee high purity and batch-to-batch consistency. A purity of ≥98.0% by HPLC is typically required for reliable results in complex organic synthesis. Chinese chemical manufacturers have emerged as significant players in the global supply chain for pharmaceutical intermediates and specialty amino acids, offering competitive pricing and robust production capabilities. Identifying a reliable supplier often involves reviewing their product specifications, adherence to quality control standards, and customer testimonials.

For research and development teams, procuring Fmoc-Asp-OAll is a critical investment. Whether for academic research, pharmaceutical development, or the production of custom peptides, the quality of this building block directly impacts the yield and purity of the final peptide product. We, as a dedicated supplier and manufacturer in China, understand these requirements and are committed to providing a superior product.
