In the dynamic field of custom peptide synthesis, the selection of high-quality building blocks is paramount. Fmoc-Asp-OAll, scientifically recognized as N-alpha-Fmoc-L-Aspartic Acid Alpha-Allyl Ester and bearing the CAS number 144120-53-6, is a highly sought-after intermediate. Its specific chemical structure and orthogonal protection strategy make it an essential component for creating peptides with precise modifications. As a dedicated manufacturer and supplier, we provide this crucial reagent to meet the exacting demands of the peptide synthesis industry.

The primary utility of Fmoc-Asp-OAll lies in its application within the Fmoc solid-phase peptide synthesis (SPPS) methodology. The N-terminal Fmoc group is base-labile, allowing for facile removal during peptide chain elongation. Concurrently, the allyl ester protecting the beta-carboxyl side chain of aspartic acid offers an orthogonal deprotection pathway. This allyl ester can be selectively cleaved using palladium-based reagents, a process that is milder and more selective than acid-based cleavage methods, thereby preserving other acid-sensitive protecting groups. This feature is particularly important for synthesizing peptides with complex structures or for those requiring specific side-chain manipulations. Typically supplied as a white powder, Fmoc-Asp-OAll requires storage at 2-8°C to maintain its stability and reactivity.

For researchers and procurement specialists needing to buy Fmoc-Asp-OAll, choosing a reliable manufacturer is key to ensuring product quality and consistency. Purity levels, often verified through HPLC analysis, are typically expected to be 98% or higher to guarantee successful and reproducible synthesis outcomes. Chinese manufacturers have established themselves as significant global suppliers of fine chemicals and pharmaceutical intermediates, offering a compelling combination of advanced manufacturing capabilities and competitive pricing. We are proud to be among these leading suppliers, committed to delivering exceptional quality for your custom peptide synthesis projects.
