Description
CATO manufactures Iomeprol Impurity 9 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
CATO supplies Iomeprol Impurity 9 (CAS CATO-C4X-18209), a pharmacopoeial impurity reference standard (molecular formula C17H22ClI2N3O8, MW 685.63 g/mol) used for the identification and quantification of trace impurities in APIs.
The molecular framework of Iomeprol Impurity 9 (C17H22ClI2N3O8) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine/iodine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
