Compared with other compounds in its class, the molecular weight of 254.32 g/mol gives Bicalutamide Impurity 22 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
As a process- or degradation-related impurity, Bicalutamide Impurity 22 (CAS 405-31-2, C12H8F2S2) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Bicalutamide Impurity 22 (C12H8F2S2) contains sulfur-containing functionality, fluorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
As a certified reference material (CRM), Bicalutamide Impurity 22 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.
