Description
Dapoxetine Impurity 56 (CAS 2245197-07-1 (free base)) is a certified pharmaceutical impurity reference standard with the molecular formula C30H31NOHCl and a molecular weight of 458.04 g/mol.
Dapoxetine Impurity 56 (C30H31NOHCl) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
As a certified reference material (CRM), Dapoxetine Impurity 56 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.
