Chemical Structure
Description
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.
Aripiprazole Impurity 59 (CAS CATO-C4X-100859) is a certified pharmaceutical impurity reference standard with the molecular formula C16H17Cl4N3HCl and a molecular weight of 429.59 g/mol.
Based on its molecular formula C16H17Cl4N3HCl, Aripiprazole Impurity 59 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 429.59 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), Aripiprazole Impurity 59 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.
