N-Nitroso Quetiapine EP Impurity G CAS CATO-C4X-124470

Description

Compared with other compounds in its class, the molecular weight of 256.28 g/mol gives N-Nitroso Quetiapine EP Impurity G distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

N-Nitroso Quetiapine EP Impurity G (CAS CATO-C4X-124470) is a certified pharmaceutical impurity reference standard with the molecular formula C13H8N2O2S and a molecular weight of 256.28 g/mol.

N-Nitroso Quetiapine EP Impurity G (C13H8N2O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, 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).

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.

CATO manufactures N-Nitroso Quetiapine EP Impurity G under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
