L-ARGININE-N-FMOC, PBF-OH (15N4) (CONTAINS SOLVENT) is a protected, isotopically labeled amino acid derivative based on L-arginine, bearing an N-Fmoc group on the α-amino functionality and a PBF (Pbf) side-chain protecting group on the guanidinium moiety, with four nitrogen atoms enriched as 15N. The molecule contains the free carboxylic acid (PBF-OH) and retains a protected guanidinium side chain, while the stereochemistry corresponds to the L-arginine scaffold indicated in the name. As an Fmoc/Pbf-protected, 15N-labeled building block, it is used in solid-phase or solution-phase peptide synthesis and in structure-function or analytical studies where incorporation of an isotopic nitrogen label supports NMR- or mass spectrometry-based tracking of arginine-containing peptide segments, with the noted solvent content reflecting the supplied physical form.
