Description
As a certified reference material (CRM), Iopamidol EP Impurity I 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.
CATO supplies Iopamidol EP Impurity I (CAS CATO-C4X-145010), a pharmacopoeial impurity reference standard (molecular formula C17H22ClI2N3O8, MW 685.63 g/mol) used for the identification and quantification of trace impurities in APIs.
Iopamidol EP Impurity I (C17H22ClI2N3O8) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine/iodine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
