The occurrence of O-Desmethylpimobendan D4 is closely related to deuterium isotope labeling, a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
O-Desmethylpimobendan D4 (CAS CATO-C4X-246113), molecular formula C18H12D4N4O2 and molecular weight 324.37 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C18H12D4N4O2, O-Desmethylpimobendan D4 contains deuterium isotope labeling, a steroid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 324.37 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), O-Desmethylpimobendan D4 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.
