Finerenone Impurity 50(Mixture of Z and E Isomers) CAS 1050477-39-8

Description

Compared with other compounds in its class, the molecular weight of 298.29 g/mol gives Finerenone Impurity 50(Mixture of Z and E Isomers) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

As a process- or degradation-related impurity, Finerenone Impurity 50(Mixture of Z and E Isomers) (CAS 1050477-39-8, C16H14N2O4) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Finerenone Impurity 50(Mixture of Z and E Isomers) (C16H14N2O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
