<SC>DL</SC>-Aspartate-1,4-<SUP>13</SUP>C<SUB>2</SUB> CAS 101247-29-4

Description

Compared with other compounds in its class, the molecular weight of 135.09 g/mol gives <SC>DL</SC>-Aspartate-1,4-<SUP>13</SUP>C<SUB>2</SUB> distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies <SC>DL</SC>-Aspartate-1,4-<SUP>13</SUP>C<SUB>2</SUB> (CAS 101247-29-4), a certified reference material (molecular formula C2[13C]2H7NO4, MW 135.09 g/mol) for analytical method development and quality control.

<SC>DL</SC>-Aspartate-1,4-<SUP>13</SUP>C<SUB>2</SUB> (C2[13C]2H7NO4) contains an amino-acid-derived structure, an amide group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
