Description
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.
Paroxetine Hydrochloride Hemihydrate EP Impurity F (CAS 2105932-71-4) is a certified pharmaceutical impurity reference standard with the molecular formula C39H40F2N2O6 and a molecular weight of 670.74 g/mol.
Structurally, Paroxetine Hydrochloride Hemihydrate EP Impurity F (C39H40F2N2O6) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 20.0, corresponding to approximately 20 ring(s) or double-bond equivalent(s). With a molecular weight of 670.74 g/mol, it falls into the high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), Paroxetine Hydrochloride Hemihydrate EP Impurity F 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.
