Chemical Structure

Isavuconazole Impurity N8 CAS 241479-75-4 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Isavuconazole Impurity N8.

CATO supplies Isavuconazole Impurity N8 (CAS 241479-75-4), a pharmacopoeial impurity reference standard (molecular formula C13H14F2N4O2, MW 296.27 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C13H14F2N4O2, Isavuconazole Impurity N8 contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 296.27 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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 N8 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.
