Compared with other compounds in its class, the molecular weight of 807.11 g/mol gives Ioversol Impurity 5 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
As a process- or degradation-related impurity, Ioversol Impurity 5 (CAS 104517-96-6, C18H24I3N3O9) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Ioversol Impurity 5 (C18H24I3N3O9) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
CATO manufactures Ioversol Impurity 5 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.
