L-METHIONINE-N-FMOC (1-13C) is an isotopically labeled, Fmoc-protected methionine amino acid derivative in which the methionine side chain contains a thioether and the amino group is carbamated with an Fmoc group, while the carboxyl functionality remains available as part of the protected amino acid framework. The molecule bears an Fmoc-protected α-amino group and a free carboxyl group (as indicated by the N-FMOC designation), and the "(1-13C)" label indicates incorporation of 13C at the specified carbon position within the methionine skeleton, enabling isotopic tracking in analytical or synthetic workflows. It is used as a labeled building block for peptide synthesis and for preparing methionine-containing peptide or amino acid derivatives where 13C labeling supports mass spectrometric characterization, isotopic tracing, or structure-property studies of methionine incorporation.
