Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 134.13 g/mol gives Pentanedioic-3,3-d2 Acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Pentanedioic-3,3-d2 Acid (CAS 43087-19-0), molecular formula C5H6D2O4 and molecular weight 134.13 g/mol, is a CATO reference standard with documented purity and traceability.
Pentanedioic-3,3-d2 Acid (C5H6D2O4) contains deuterium isotope labeling, a carbohydrate-derived structure. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), Pentanedioic-3,3-d2 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.
