L-ALANINE-N-FMOC (13C3; 15N) is a protected amino acid derivative of L-alanine in which the amino group is carbamated with an Fmoc (9-fluorenylmethoxycarbonyl) protecting group, while the side chain remains a methyl group typical of alanine. The molecule bears a free carboxylic acid functionality and an Fmoc-protected nitrogen, and it is isotopically labeled with three 13C atoms and one 15N atom as indicated by the product name. In peptide and amino acid synthesis workflows, the Fmoc-protected, isotopically labeled alanine is used as a building block for incorporating labeled residues into peptides and for supporting NMR- or mass spectrometry-based analytical studies of peptide structure, labeling patterns, and reaction products.
