Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 235.28 g/mol gives Cabazitaxel Impurity 17 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Cabazitaxel Impurity 17 (CAS 160535-69-3) is a certified pharmaceutical impurity reference standard with the molecular formula C13H17NO3 and a molecular weight of 235.28 g/mol.
Structurally, Cabazitaxel Impurity 17 (C13H17NO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 235.28 g/mol, it falls into the medium-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
