Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 356.50 g/mol gives Palonosetron Impurity 43 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Palonosetron Impurity 43 (CAS CATO-C4X-110543) is a certified pharmaceutical impurity reference standard with the molecular formula C22H32N2O2 and a molecular weight of 356.50 g/mol.
Based on its molecular formula C22H32N2O2, Palonosetron Impurity 43 contains a steroid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 356.50 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
