Fmoc-L-Arg(Pbf)-Wang

Fmoc-L-Arg(Pbf)-Wang is an Fmoc-protected L-arginine with a 2,2,4,6,7-pentamethyl-dihydrobenzofuran-5-sulfonyl (Pbf) protecting group on the guanidino group, attached to Wang resin. This reagent is essential for SPPS, allowing the incorporation of arginine residues with protected side chains.
