Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Isavuconazole Impurity 121 Iodization HCl.
CATO supplies Isavuconazole Impurity 121 Iodization HCl (CAS CATO-C4X-1236121), a pharmacopoeial impurity reference standard (molecular formula C39H45F2N8O6SIHCl, MW 955.25 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C39H45F2N8O6SIHCl, Isavuconazole Impurity 121 Iodization HCl contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine/iodine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 955.25 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.
As a certified reference material (CRM), Isavuconazole Impurity 121 Iodization HCl meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
