Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 313.39 g/mol gives Ezetimibe Impurity 114 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Ezetimibe Impurity 114 (CAS CATO-C4X-1098114) is a certified pharmaceutical impurity reference standard with the molecular formula C19H23NO3 and a molecular weight of 313.39 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, Ezetimibe Impurity 114 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 313.39 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
