Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 306.62 g/mol gives Etoricoxib Impurity 5(hexafluorophosphate) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
As a process- or degradation-related impurity, Etoricoxib Impurity 5(hexafluorophosphate) (CAS 291756-76-8, C7H14ClN2F6P) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Etoricoxib Impurity 5(hexafluorophosphate) (C7H14ClN2F6P) contains organophosphorus functionality, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
As a certified reference material (CRM), Etoricoxib Impurity 5(hexafluorophosphate) 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.
