Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 327.44 g/mol gives Quinidine-d3 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Quinidine-d3 (CAS 1267657-68-0), molecular formula C20H21D3N2O2 and molecular weight 327.44 g/mol, is a CATO reference standard with documented purity and traceability.
Quinidine-d3 (C20H21D3N2O2) contains deuterium isotope labeling, a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), Quinidine-d3 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.
