GA21745

Fmoc-N-Me-Arg(Pbf)-OH

Also known as (2S)-5-[[amino-[(2,2,4,6,7-pentamethyl-3H-1-benzofuran-5-yl)sulfonylamino]methylidene]amino]-2-[9H-fluoren-9-ylmethoxycarbonyl(methyl)amino]pentanoic acid

Derivative for synthesizing peptides containing Nα-methylated arginine, superior to Fmoc-N-Me-Arg(Mtr)-OH (4026642), as Pbf can be removed under much milder conditions
