L-Arginine-13C6,15N4 Na-Fmoc-Nw-Pbf derivative is a carbon-13 and nitrogen-15 labeled version of L-arginine, an amino acid essential for protein synthesis and nitric oxide production. The Fmoc (9-fluorenylmethoxycarbonyl) and Pbf (2,2,4,6,7-pentamethyldihydrobenzofuran-5-sulfonyl) groups are protecting groups used in peptide synthesis to prevent unwanted reactions. This labeled derivative is used in peptide chemistry for the synthesis of high-purity peptides, particularly in structural and functional studies. The stable isotopes (13C and 15N) facilitate detailed mass spectrometry and NMR spectroscopy analysis, aiding in the accurate determination of peptide structure, conformation, and interactions in various biochemical and pharmaceutical applications.
