L-PHENYLALANINE (15N) is an isotopically labeled form of the proteinogenic amino acid phenylalanine, featuring a benzyl side chain attached to the alpha carbon and an amino acid backbone suitable for peptide incorporation. The molecule contains a primary amino group and a carboxyl group, with the nitrogen atom labeled as 15N within the amino functionality while the remaining structure corresponds to the unlabeled L-phenylalanine framework. As a 15N-labeled phenylalanine analogue, it is used for stable-isotope tracing, NMR or mass spectrometric method development, and quantitative studies that track incorporation or exchange of the amino-nitrogen during peptide and protein-related workflows.
