Chemical Structure

Gadobutrol impurity 177 CAS CATO-C4X-2120177 chemical structure

Description

Gadobutrol impurity 177 (C20H40N4O10) 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.

Gadobutrol impurity 177 (CAS CATO-C4X-2120177) is a certified pharmaceutical impurity reference standard with the molecular formula C20H40N4O10 and a molecular weight of 496.55 g/mol.

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.
