Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 337.33 g/mol gives Cinitapride Impurity 32 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Cinitapride Impurity 32 (CAS CATO-C4X-290832) is a certified pharmaceutical impurity reference standard with the molecular formula C14H19N5O5 and a molecular weight of 337.33 g/mol.
Based on its molecular formula C14H19N5O5, Cinitapride Impurity 32 contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 337.33 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.
