Chemical Structure

Gadobutrol Impurity 140 4HCl CAS CATO-C4X-2120140 chemical structure

Description

CATO supplies Gadobutrol Impurity 140 4HCl (CAS CATO-C4X-2120140), a pharmacopoeial impurity reference standard (molecular formula C16H32N4O7HCl, MW 428.91 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Gadobutrol Impurity 140 4HCl (C16H32N4O7HCl) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine 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.

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.

As a certified reference material (CRM), Gadobutrol Impurity 140 4HCl meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
