Chemical Structure

Ticagrelor impurity 162 HCl CAS 1643378-54-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 205.63 g/mol gives Ticagrelor impurity 162 HCl distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Ticagrelor impurity 162 HCl (CAS 1643378-54-4) is a certified pharmaceutical impurity reference standard with the molecular formula C9H9F2NHCl and a molecular weight of 205.63 g/mol.

Ticagrelor impurity 162 HCl (C9H9F2NHCl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
