Chemical Structure

Maribavir Impurity 32 CAS CATO-C4X-300732 chemical structure

Description

The molecular framework of Maribavir Impurity 32 (C13H14Cl2N2O5) is characterized by a nitrogen-containing heterocyclic scaffold, an amide 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Maribavir Impurity 32 (CAS CATO-C4X-300732) is a certified pharmaceutical impurity reference standard with the molecular formula C13H14Cl2N2O5 and a molecular weight of 349.17 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.

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.
