Clopidogrel Impurity 109 CAS 2109017-75-4(free base)

Description

Compared with other compounds in its class, the molecular weight of 358.28 g/mol gives Clopidogrel Impurity 109 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Clopidogrel Impurity 109 (CAS 2109017-75-4(free base)) is a certified pharmaceutical impurity reference standard with the molecular formula C16H16ClNO2SHCl and a molecular weight of 358.28 g/mol.

Clopidogrel Impurity 109 (C16H16ClNO2SHCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

As a certified reference material (CRM), Clopidogrel Impurity 109 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
