Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
53931-70-7 dl-glutamic acid-3,3-d2 (CAS 53931-70-7), molecular formula C5H7D2NO4 and molecular weight 149.14 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 53931-70-7 dl-glutamic acid-3,3-d2 (C5H7D2NO4) is characterized by deuterium isotope labeling, a carbohydrate-derived structure, an amide group. 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
As a certified reference material (CRM), 53931-70-7 dl-glutamic acid-3,3-d2 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.
