Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 1076.53 g/mol gives Isavuconazole Impurity 56 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Isavuconazole Impurity 56 (CAS CATO-C4X-123656) is a certified pharmaceutical impurity reference standard with the molecular formula C49H52F2N11O11SCl and a molecular weight of 1076.53 g/mol.
Structurally, Isavuconazole Impurity 56 (C49H52F2N11O11SCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 28.0, corresponding to approximately 28 ring(s) or double-bond equivalent(s). With a molecular weight of 1076.53 g/mol, it falls into the high-molecular-weight range. 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 56 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.
