Chemical Structure

Gadobutrol Impurity 123 CAS CATO-C4X-2120123 chemical structure

Description

The molecular framework of Gadobutrol Impurity 123 (C18H38N4O8) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage. 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.

Gadobutrol Impurity 123 (CAS CATO-C4X-2120123) is a certified pharmaceutical impurity reference standard with the molecular formula C18H38N4O8 and a molecular weight of 438.52 g/mol.

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 Gadobutrol Impurity 123 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.
