Chemical Structure
Description
Gadobutrol Impurity 141 (C16H32N4O7) 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO supplies Gadobutrol Impurity 141 (CAS CATO-C4X-2120141), a pharmacopoeial impurity reference standard (molecular formula C16H32N4O7, MW 392.45 g/mol) used for the identification and quantification of trace impurities in APIs.
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
