Description
Vinpocetine Impurity 39 (CAS 27773-39-3) is a certified pharmaceutical impurity reference standard with the molecular formula C22H26N2O3 and a molecular weight of 366.45 g/mol.
Based on its molecular formula C22H26N2O3, Vinpocetine Impurity 39 contains 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 366.45 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 supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
As a certified reference material (CRM), Vinpocetine Impurity 39 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.
