Topiroxostat impurity 69 CAS CATO-C4X-105569 chemical structure

Description

Topiroxostat impurity 69 (CAS CATO-C4X-105569) is a certified pharmaceutical impurity reference standard with the molecular formula C14H7N7 and a molecular weight of 273.25 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, Topiroxostat impurity 69 is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 273.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
