Chemical Structure

Isavuconazole Impurity 231 CAS CATO-C4X-1236231 chemical structure

Description

CATO manufactures Isavuconazole Impurity 231 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.

CATO supplies Isavuconazole Impurity 231 (CAS CATO-C4X-1236231), a pharmacopoeial impurity reference standard (molecular formula C31H23F2N6O2SI, MW 708.52 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/iodine substitution, Isavuconazole Impurity 231 is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 708.52 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
