Chemical Structure
Description
The occurrence of Gadoxetate Impurity 9 is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Gadoxetate Impurity 9 (CAS CATO-C4X-26189) is a certified pharmaceutical impurity reference standard with the molecular formula C24H38N4O2HCl and a molecular weight of 451.05 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, Gadoxetate Impurity 9 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 451.05 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 Gadoxetate Impurity 9 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.
