Compared with other compounds in its class, the molecular weight of 429.25 g/mol gives Cariprazine Impurity 56 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Cariprazine Impurity 56 (CAS CATO-C4X-240856), a pharmacopoeial impurity reference standard (molecular formula C18H28Cl2N3HClCl, MW 429.25 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C18H28Cl2N3HClCl, Cariprazine Impurity 56 contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 429.25 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
