Description
As a certified reference material (CRM), Etrasimod Impurity 25 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.
Etrasimod Impurity 25 (CAS CATO-C4X-321425) is a certified pharmaceutical impurity reference standard with the molecular formula C26H26F3NO4 and a molecular weight of 473.48 g/mol.
Based on its molecular formula C26H26F3NO4, Etrasimod Impurity 25 contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 473.48 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.
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.
