L-GLUTAMINE-N-FMOC (13C5,15N2) is an isotopically labeled, protected amino acid derivative corresponding to L-glutamine bearing an N-Fmoc (9-fluorenylmethoxycarbonyl) group on the amino functionality and isotopic enrichment at the carbon and nitrogen positions indicated by (13C5,15N2). The molecule retains the glutamine side chain with a terminal amide, features a carboxyl group as part of the glutamine backbone, and presents the stereochemistry consistent with the L-glutamine parent while the N-Fmoc protection masks the α-amino group to control chemoselectivity during peptide assembly. In synthesis and analytical workflows, it is used as a labeled building block for solid-phase or solution-phase peptide synthesis and for preparing glutamine-containing peptides or conjugates where 13C/15N labeling supports mass spectrometric detection, isotopic tracing, or structure-property studies.
