L-PHENYLALANINE (1-13C) is an isotopically labeled, proteinogenic amino acid in which the carbon-13 label is incorporated at the 1-position of the phenylalanine backbone, retaining the standard phenylalanine side chain. The molecule contains a free amino group and a free carboxyl group along with a benzyl (phenylmethyl) side chain, and its stereochemistry corresponds to the L-phenylalanine configuration as indicated by the product name. As an isotopically enriched tracer, it is used in amino acid metabolism studies, peptide/protein labeling workflows, and analytical method development where 13C NMR or mass spectrometry detection of labeled fragments is required.
CAT No: L-Iso-0477
