Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 444.01 g/mol gives Dapoxetine Impurity 8 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Dapoxetine Impurity 8 (CAS CATO-C4X-14398) is a certified pharmaceutical impurity reference standard with the molecular formula C29H29NOHCl and a molecular weight of 444.01 g/mol.
Based on its molecular formula C29H29NOHCl, Dapoxetine Impurity 8 contains a steroid 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 444.01 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), Dapoxetine Impurity 8 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.
