Isavuconazole Impurity 26 CAS CATO-C4X-123626

Description

The occurrence of Isavuconazole Impurity 26 is closely related to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Isavuconazole Impurity 26 (CAS CATO-C4X-123626) is a certified pharmaceutical impurity reference standard with the molecular formula C22H17F2N5OS and a molecular weight of 437.47 g/mol.

Based on its molecular formula C22H17F2N5OS, Isavuconazole Impurity 26 contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 437.47 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.

CATO manufactures Isavuconazole Impurity 26 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.
