Compared with other compounds in its class, the molecular weight of 557.52 g/mol gives Enzalutamide Impurity 52 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Enzalutamide Impurity 52 (CAS CATO-C4X-101652) is a certified pharmaceutical impurity reference standard with the molecular formula C27H19F4N3O4S and a molecular weight of 557.52 g/mol.
The molecular framework of Enzalutamide Impurity 52 (C27H19F4N3O4S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), Enzalutamide Impurity 52 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.
