Chemical Structure

Gadobenate Dimeglumine impurity 10 CAS 13811-41-1 chemical structure

Description

The occurrence of Gadobenate Dimeglumine impurity 10 is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

As a process- or degradation-related impurity, Gadobenate Dimeglumine impurity 10 (CAS 13811-41-1, C12H21N3O8) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Gadobenate Dimeglumine impurity 10 (C12H21N3O8) contains an amino-acid-derived structure, an amide 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).

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.
