Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 406.48 g/mol gives Finerenone Impurity 153 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Finerenone Impurity 153 (CAS CATO-C4X-2880153), a pharmacopoeial impurity reference standard (molecular formula C23H26N4O3, MW 406.48 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C23H26N4O3, Finerenone Impurity 153 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 406.48 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
