L-ASPARTIC ACID-N-FMOC, BETA-O-TERT- BUTYL ESTER (13C4,15N) is a protected, isotopically labeled aspartic acid derivative in which the α-amino group is capped with an Fmoc protecting group and the β-carboxyl functionality is esterified as a tert-butyl ester. The molecule contains an α-carboxylic acid group and an Fmoc carbamate, while the β-O-tert-butyl ester masks the side-chain carboxyl for chemoselective peptide-coupling chemistry, and the (13C4,15N) labeling is distributed over the carbon and nitrogen framework indicated by the product name. In peptide synthesis workflows and related analytical studies, this protected labeled amino acid is used as a substrate building block to incorporate the aspartate side chain under controlled protection patterns and to enable isotopic tracing or mass spectrometric quantification of aspartate-containing peptide or amino-acid derivative products.
CAT No: L-Iso-0143
