Isavuconazole Impurity 70 CAS CATO-C4X-123670

Description

The occurrence of Isavuconazole Impurity 70 is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Isavuconazole Impurity 70 (CAS CATO-C4X-123670), a pharmacopoeial impurity reference standard (molecular formula C40H45F2N8O8S, MW 835.90 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C40H45F2N8O8S, Isavuconazole Impurity 70 contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 835.90 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).

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.

As a certified reference material (CRM), Isavuconazole Impurity 70 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
