L-LEUCINE-N-FMOC (13C6) is an isotopically labeled, protected amino acid derivative in which L-leucine is converted to the N-Fmoc (9H-fluoren-9-ylmethoxycarbonyl) carbamate, with six carbon atoms enriched to 13C. The molecule retains the free carboxylic acid functional group and bears the hydrophobic isobutyl side chain characteristic of leucine, while the amino functionality is masked as the FMOC-protected carbamate to control chemoselectivity during peptide assembly. The 13C labeling provides an isotopic handle for NMR or mass spectrometric tracking in peptide and amino-acid derivative synthesis, and the FMOC protection supports stepwise incorporation of the labeled residue in solid-phase or solution-phase peptide chemistry workflows.
CAT No: L-Iso-0378
