Chemical Structure
Description
The occurrence of Isavuconazole Impurity 68 is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Isavuconazole Impurity 68 (CAS CATO-C4X-123668), a pharmacopoeial impurity reference standard (molecular formula C34H35F2N8O6SCl, MW 757.21 g/mol) used for the identification and quantification of trace impurities in APIs.
Structurally, Isavuconazole Impurity 68 (C34H35F2N8O6SCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 20.0, corresponding to approximately 20 ring(s) or double-bond equivalent(s). With a molecular weight of 757.21 g/mol, it falls into the high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 68 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.
