Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 575.39 g/mol gives Isavuconazole Impurity 149 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Isavuconazole Impurity 149 (CAS CATO-C4X-1236149) is a certified pharmaceutical impurity reference standard with the molecular formula C23H25F2N6O5HClCl and a molecular weight of 575.39 g/mol.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, Isavuconazole Impurity 149 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 575.39 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 Isavuconazole Impurity 149 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.
