Isavuconazole Impurity 47 CAS CATO-C4X-123647

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 47.

CATO supplies Isavuconazole Impurity 47 (CAS CATO-C4X-123647), a pharmacopoeial impurity reference standard (molecular formula C15H23N3O4, MW 309.36 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Isavuconazole Impurity 47 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 309.36 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 47 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.
