Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Brexpiprazole Impurity 94.
CATO supplies Brexpiprazole Impurity 94 (CAS CATO-C4X-113194), a pharmacopoeial impurity reference standard (molecular formula C17H21BrClNO2, MW 386.71 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C17H21BrClNO2, Brexpiprazole Impurity 94 contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 386.71 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.
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.
As a certified reference material (CRM), Brexpiprazole Impurity 94 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.
