Isavuconazole Impurity 183 CAS CATO-C4X-1236183

Description

The occurrence of Isavuconazole Impurity 183 is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine/iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Isavuconazole Impurity 183 (CAS CATO-C4X-1236183), a pharmacopoeial impurity reference standard (molecular formula C37H40F2N7O7SIHCl, MW 928.18 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C37H40F2N7O7SIHCl, Isavuconazole Impurity 183 contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine/iodine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 928.18 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

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.
