Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 265.31 g/mol gives Apalutamide Impurity 25 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Apalutamide Impurity 25 (CAS CATO-C4X-274925), a pharmacopoeial impurity reference standard (molecular formula C13H19N3O3, MW 265.31 g/mol) used for the identification and quantification of trace impurities in APIs.
Apalutamide Impurity 25 (C13H19N3O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
CATO manufactures Apalutamide Impurity 25 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
