Chemical Structure

Maribavir Impurity 17 CAS CATO-C4X-300717 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 206.24 g/mol gives Maribavir Impurity 17 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Maribavir Impurity 17 (CAS CATO-C4X-300717) is a certified pharmaceutical impurity reference standard with the molecular formula C9H18O5 and a molecular weight of 206.24 g/mol.

Maribavir Impurity 17 (C9H18O5) contains 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.

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.
