Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including D-Glutamic-2,3,3,4,4-d5 Acid.
D-Glutamic-2,3,3,4,4-d5 Acid (CAS 14341-88-9), molecular formula C5H4D5NO4 and molecular weight 152.16 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of D-Glutamic-2,3,3,4,4-d5 Acid (C5H4D5NO4) 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).
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.
As a certified reference material (CRM), D-Glutamic-2,3,3,4,4-d5 Acid 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.
