Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 392.79 g/mol gives Cariprazine Impurity 11 DiHCl distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Cariprazine Impurity 11 DiHCl (CAS CATO-C4X-240811) is a certified pharmaceutical impurity reference standard with the molecular formula C18H27Cl2N3HCl and a molecular weight of 392.79 g/mol.
Cariprazine Impurity 11 DiHCl (C18H27Cl2N3HCl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
