Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 390.45 g/mol gives Tafluprost Impurity 2 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Tafluprost Impurity 2 (CAS CATO-C4X-21632) is a certified pharmaceutical impurity reference standard with the molecular formula C22H27FO5 and a molecular weight of 390.45 g/mol.
Based on its molecular formula C22H27FO5, Tafluprost Impurity 2 contains a flavonoid core, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 390.45 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), Tafluprost Impurity 2 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.
