Description
As a certified reference material (CRM), Apalutamide Impurity 98 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 Apalutamide Impurity 98 (CAS CATO-C4X-274998), a pharmacopoeial impurity reference standard (molecular formula C28H32F2N4O5, MW 542.57 g/mol) used for the identification and quantification of trace impurities in APIs.
Apalutamide Impurity 98 (C28H32F2N4O5) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
