Isavuconazole impurity 65 CAS CATO-C4X-1236165

Description

The occurrence of Isavuconazole impurity 65 is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Isavuconazole impurity 65 (CAS CATO-C4X-1236165) is a certified pharmaceutical impurity reference standard with the molecular formula C17H21F2N3O3 and a molecular weight of 353.36 g/mol.

Based on its molecular formula C17H21F2N3O3, Isavuconazole impurity 65 contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 353.36 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).

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.
