Description
Bedaquiline Impurity 21 (CAS 1228594-68-0) is a certified pharmaceutical impurity reference standard with the molecular formula C31H28BrClN2O and a molecular weight of 559.92 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, Bedaquiline Impurity 21 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 559.92 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), Bedaquiline Impurity 21 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.
