Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 411.79 g/mol gives Aripiprazole Impurity 79 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
As a process- or degradation-related impurity, Aripiprazole Impurity 79 (CAS CATO-C4X-100879, C18H28Cl2N2O2HCl) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Aripiprazole Impurity 79 (C18H28Cl2N2O2HCl) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, 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.
As a certified reference material (CRM), Aripiprazole Impurity 79 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.
