L-PHENYLALANINE-N-T-BOC (15N) is a protected, isotopically labeled amino acid derivative in which phenylalanine bears an N-tert-butoxycarbonyl (Boc) protecting group and a 15N label on the amino nitrogen. The molecule contains a free carboxylic acid functional group and a side chain with a benzyl aromatic ring, while the Boc group masks the alpha-amino functionality to control chemoselectivity during peptide coupling. It is employed as an isotopically labeled building block for solid-phase or solution-phase peptide synthesis and for analytical method development and structural studies where incorporation of a defined 15N site is used for mass spectrometric or NMR-based tracing.
