Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 267.24 g/mol gives Isavuconazole Impurity 213 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Isavuconazole Impurity 213 (CAS CATO-C4X-1236213), a pharmacopoeial impurity reference standard (molecular formula C10H13N5O4, MW 267.24 g/mol) used for the identification and quantification of trace impurities in APIs.
Isavuconazole Impurity 213 (C10H13N5O4) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
