Product Technical Details

Product Overview

Fmoc-D-Arg(Pbf)-OH is a highly specialized protected amino acid derivative designed for use in advanced solid-phase peptide synthesis (SPPS). As a critical building block, this compound features the Fmoc (9-fluorenylmethoxycarbonyl) protecting group on the alpha-amino function and the Pbf (2,2,4,6,7-pentamethyl-2,3-dihydrobenzofuran-5-sulfonyl) group on the guanidine side chain. This specific configuration ensures exceptional stability during chain elongation while allowing for efficient deprotection under standard acidic cleavage conditions.

Our manufacturing process adheres to strict quality control protocols to ensure consistent optical purity and chemical integrity. The D-configuration of the arginine residue is particularly valuable for researchers developing peptide therapeutics that require enhanced metabolic stability or specific conformational properties. By incorporating D-amino acids, pharmaceutical scientists can modulate the biological activity and half-life of peptide candidates during the early stages of drug discovery.
