L-ASPARTIC ACID-N-ALPHA-CBZ (13C4) is a 13C-labeled, protected amino acid derivative in which the aspartic acid α-amino group is carbamated with a benzyloxycarbonyl (Cbz) protecting group, while the side chain retains the β-carboxylic acid functionality characteristic of the aspartate class. The molecule bears a free carboxylic acid at the α-position and an additional carboxyl group at the β-position, and the stereochemistry is specified as L for the α-carbon; the Cbz group masks the α-amino functionality to control chemoselectivity during peptide coupling chemistry. As an isotopically labeled, Cbz-protected building block, it is used in peptide synthesis workflows and in analytical or chemical biology studies that require carbon-13 tracing for mass spectrometry-based quantification of aspartate-containing fragments or derivatives.
