Nifuratel Impurity 20 CAS CATO-C4X-127220

Description

Compared with other compounds in its class, the molecular weight of 285.28 g/mol gives Nifuratel Impurity 20 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Nifuratel Impurity 20 (CAS CATO-C4X-127220) is a certified pharmaceutical impurity reference standard with the molecular formula C10H11N3O5S and a molecular weight of 285.28 g/mol.

Nifuratel Impurity 20 (C10H11N3O5S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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. 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.
