Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 404.59 g/mol gives Gadoteridol Impurity 5 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Gadoteridol Impurity 5 (CAS 148407-91-4) is a certified pharmaceutical impurity reference standard with the molecular formula C20H44N4O4 and a molecular weight of 404.59 g/mol.
Gadoteridol Impurity 5 (C20H44N4O4) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.
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 manufactures Gadoteridol 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.
