Chemical Structure
Description
The occurrence of <I>N</I>-acetyl-<SC>L</SC>-aspartic acid-1,2,3,4-<SUP>13</SUP>C<SUB>4</SUB > is closely related to an amino-acid-derived structure, an amide group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
<I>N</I>-acetyl-<SC>L</SC>-aspartic acid-1,2,3,4-<SUP>13</SUP>C<SUB>4</SUB > (CAS 1217460-88-2), molecular formula C2[13C]4H9NO5 and molecular weight 179.11 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of <I>N</I>-acetyl-<SC>L</SC>-aspartic acid-1,2,3,4-<SUP>13</SUP>C<SUB>4</SUB > (C2[13C]4H9NO5) is characterized by an amino-acid-derived structure, an amide group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
