L-ASPARTIC ACID-N-FMOC (13C4,15N) is an isotopically labeled, Fmoc-protected derivative of the amino acid aspartic acid, featuring a side chain with a terminal carboxylic acid. The molecule contains an Fmoc carbamate on the amino group and a free carboxyl group on the side chain along with the carboxylic acid functionality at the α-position, and it is specified as the L stereochemical form while bearing 13C4 and 15N isotopic labels for tracing and mass-based detection. In peptide and amino acid derivative synthesis, the N-Fmoc protection supports stepwise assembly by controlling chemoselectivity at the amino functionality, while the isotopic enrichment enables incorporation into peptides or analytical standards for LC-MS-based quantification, isotopic labeling experiments, and structural characterization.
CAT No: L-Iso-0141
