L-ASPARTIC ACID-N-FMOC, BETA-O-TERT-BUTYL ESTER (15N) is a protected amino acid derivative of aspartic acid bearing an N-Fmoc group on the amino functionality and a beta-O-tert-butyl ester on the side-chain carboxyl group, with the backbone nitrogen isotopically labeled as 15N. The molecule contains a free carboxyl group at the alpha position while the side-chain carboxyl is masked as a tert-butyl ester, and the stereochemistry corresponds to the L-form indicated by the product name. In peptide synthesis workflows, the Fmoc-protected amino group supports stepwise assembly on solid or solution-phase supports, while the 15N label enables incorporation of an isotopic marker for NMR or mass spectrometry-based analytical studies of peptide and amino acid derivatives.
CAT No: L-Iso-0145
