Chemical Structure
Description
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, Aripiprazole Impurity 63 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 494.86 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO supplies Aripiprazole Impurity 63 (CAS 2748462-55-5), a pharmacopoeial impurity reference standard (molecular formula C23H28BrN3O2HCl, MW 494.86 g/mol) used for the identification and quantification of trace impurities in APIs.
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), Aripiprazole Impurity 63 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.
