GLYCINE-N-FMOC (2-13C;15N) is an isotopically labeled, Fmoc-protected glycine derivative in which the amino acid backbone carries 13C at the carbon positions indicated by "2-13C" and 15N at the nitrogen, while the alpha-amino group is protected as an N-(9H-fluoren-9-ylmethoxycarbonyl) (Fmoc) carbamate. The molecule contains a free carboxylic acid functional group and an Fmoc-protected nitrogen, with the glycine side chain reduced to a single hydrogen, and the isotopic labels provide site-specific mass and NMR observability without changing the core amino acid connectivity. It is employed as a labeled building block in stepwise peptide synthesis workflows, including solid-phase peptide synthesis, and as a substrate for analytical method development where incorporation of 13C/15N at the glycine position supports isotopic tracing, mass spectrometric characterization, and structural studies of peptide or amino-acid-derived products.
