L-PHENYLALANINE-N-T-BOC (13C9,15N) is a protected amino acid derivative in which L-phenylalanine is modified at the amino group by a tert-butoxycarbonyl (Boc) protecting group, while the aromatic side chain and backbone nitrogen are isotopically labeled with 13C (9 positions) and 15N. The molecule contains a free carboxylic acid functional group and a Boc-protected α-amino group, with the phenylalanine benzyl side chain providing a hydrophobic aromatic functionality for incorporation into peptide frameworks. As an isotopically labeled, N-Boc-protected building block, it is used in peptide synthesis and analytical workflows such as mass spectrometry-based tracing and structure verification of labeled peptide or amino acid derivatives.
