As a certified reference material (CRM), Enzalutamide Impurity 27 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.
CATO supplies Enzalutamide Impurity 27 (CAS 1798807-39-2), a pharmacopoeial impurity reference standard (molecular formula C17H12F4N4OS, MW 396.36 g/mol) used for the identification and quantification of trace impurities in APIs.
Enzalutamide Impurity 27 (C17H12F4N4OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point; 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.
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.
