Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 556.02 g/mol gives Chlorhexidine Impurity 24 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Chlorhexidine Impurity 24 (CAS CATO-C4X-225624) is a certified pharmaceutical impurity reference standard with the molecular formula C22H34ClN9O6 and a molecular weight of 556.02 g/mol.
Based on its molecular formula C22H34ClN9O6, Chlorhexidine Impurity 24 contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 556.02 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), Chlorhexidine Impurity 24 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.
