L-ALANINE-N-FMOC (3-13C) is an N-Fmoc-protected derivative of the amino acid alanine in which the amino acid backbone retains an alanine side chain (methyl) and the nitrogen is substituted with a fluorenylmethoxycarbonyl (Fmoc) protecting group. The molecule contains an unprotected carboxyl functional group and an Fmoc-protected amino group, and it bears three 13C isotopic labels within the alanine framework as indicated by the product name while maintaining the L stereochemical designation for the amino acid center. This isotopically labeled, protected amino acid is used as a building block in peptide synthesis and as an NMR- or mass-spectrometry-compatible tracer for analytical studies of incorporation and labeling patterns in peptide or amino acid derivative workflows.
