L-PHENYLALANINE (13C9,D8,15N) is an isotopically labeled form of the proteinogenic amino acid L-phenylalanine, featuring a benzyl side chain attached to the alpha carbon of the amino acid backbone. The molecule contains an amino group and a carboxyl group, with nine carbon atoms, eight deuterium atoms, and one nitrogen atom incorporated as stable isotopes to enable mass-shift detection while retaining the stereochemical form indicated by the "L" designation. As a labeled amino acid, it is used in isotopic tracing, quantitative mass spectrometry and amino acid profiling, and the preparation of labeled peptide or protein fragments for structure-activity, metabolic labeling, or analytical method development.
