Chemical Structure

<SC>DL</SC>-Aspartate-1-<SUP>13</SUP>C CAS 137168-39-9 chemical structure

Description

As a certified reference material (CRM), <SC>DL</SC>-Aspartate-1-<SUP>13</SUP>C meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

<SC>DL</SC>-Aspartate-1-<SUP>13</SUP>C (CAS 137168-39-9) is a high-purity analytical reference standard with the molecular formula C3[13C]H7NO4 and a molecular weight of 134.10 g/mol.

<SC>DL</SC>-Aspartate-1-<SUP>13</SUP>C (C3[13C]H7NO4) contains a carbohydrate-derived structure, an amide group. 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.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
