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.
Polaprezinc Impurity 13 DiHCl (CAS CATO-C4X-182113) is a certified pharmaceutical impurity reference standard with the molecular formula C9H14N4O3HCl and a molecular weight of 262.69 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, Polaprezinc Impurity 13 DiHCl is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 262.69 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
