Chemical Structure
Description
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.
CATO supplies Iopromide impurity 17 (CAS 219851-74-8), a pharmacopoeial impurity reference standard (molecular formula C16H3Cl3I6N2O4, MW 1154.99 g/mol) used for the identification and quantification of trace impurities in APIs.
The molecular framework of Iopromide impurity 17 (C16H3Cl3I6N2O4) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO manufactures Iopromide impurity 17 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.
