Posaconazole Impurity 34 CAS CATO-C4X-120834

Description

Compared with other compounds in its class, the molecular weight of 498.53 g/mol gives Posaconazole Impurity 34 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Posaconazole Impurity 34 (CAS CATO-C4X-120834), a pharmacopoeial impurity reference standard (molecular formula C23H23FN6O4S, MW 498.53 g/mol) used for the identification and quantification of trace impurities in APIs.

Posaconazole Impurity 34 (C23H23FN6O4S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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 Posaconazole Impurity 34 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.
