As a certified reference material (CRM), Iobitridol Impurity 28 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 Iobitridol Impurity 28 (CAS CATO-C4X-317828), a pharmacopoeial impurity reference standard (molecular formula C15H16I3NO7, MW 703.00 g/mol) used for the identification and quantification of trace impurities in APIs.
The molecular framework of Iobitridol Impurity 28 (C15H16I3NO7) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
