Chemical Structure
Description
Structurally, Bosutinib Impurity 32 (C39H30Cl4N6O6) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 26.0, corresponding to approximately 26 ring(s) or double-bond equivalent(s). With a molecular weight of 820.50 g/mol, it falls into the high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Bosutinib Impurity 32 (CAS 2095306-27-5) is a certified pharmaceutical impurity reference standard with the molecular formula C39H30Cl4N6O6 and a molecular weight of 820.50 g/mol.
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.
