Chemical Structure
Description
The occurrence of Isavuconazole Impurity 128 is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Isavuconazole Impurity 128 (CAS CATO-C4X-1236128) is a certified pharmaceutical impurity reference standard with the molecular formula C32H30F2N7O7S2I and a molecular weight of 853.65 g/mol.
Based on its molecular formula C32H30F2N7O7S2I, Isavuconazole Impurity 128 contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/iodine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 853.65 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
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.
