Compared with other compounds in its class, the molecular weight of 332.62 g/mol gives Bedaquiline Impurity 5 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Bedaquiline Impurity 5 (CAS 654655-68-2) is a certified pharmaceutical impurity reference standard with the molecular formula C16H11BrClN and a molecular weight of 332.62 g/mol.
Structurally, Bedaquiline Impurity 5 (C16H11BrClN) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 332.62 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
CATO manufactures Bedaquiline Impurity 5 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
