Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 483.44 g/mol gives Enzalutamide Impurity 11 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Enzalutamide Impurity 11 (CAS CATO-C4X-101611) is a certified pharmaceutical impurity reference standard with the molecular formula C21H17F4N3O4S and a molecular weight of 483.44 g/mol.
Enzalutamide Impurity 11 (C21H17F4N3O4S) contains a flavonoid core, an amide group, a sulfone 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.
CATO manufactures Enzalutamide Impurity 11 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.
