Chemical Structure
Description
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, iodine substitution, Iobitridol Impurity 27 is typically off-white to pale yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 745.08 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).
CATO supplies Iobitridol Impurity 27 (CAS CATO-C4X-317827), a pharmacopoeial impurity reference standard (molecular formula C18H22I3NO7, MW 745.08 g/mol) used for the identification and quantification of trace impurities in APIs.
This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
As a certified reference material (CRM), Iobitridol Impurity 27 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.
