Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 537.49 g/mol gives Bedaquiline impurity 69 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Bedaquiline impurity 69 (CAS CATO-C4X-116769) is a certified pharmaceutical impurity reference standard with the molecular formula C32H29BrN2O and a molecular weight of 537.49 g/mol.
The molecular framework of Bedaquiline impurity 69 (C32H29BrN2O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
