Chemical Structure
Description
CATO manufactures Iobitridol Impurity 26 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 Iobitridol Impurity 26 (CAS CATO-C4X-317826), a pharmacopoeial impurity reference standard (molecular formula C19H25I3N2O8, MW 790.12 g/mol) used for the identification and quantification of trace impurities in APIs.
Iobitridol Impurity 26 (C19H25I3N2O8) 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. 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).
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.
