Clopidogrel Impurity 77 CAS CATO-C4X-102977

Description

Compared with other compounds in its class, the molecular weight of 344.25 g/mol gives Clopidogrel Impurity 77 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Clopidogrel Impurity 77 (CAS CATO-C4X-102977) is a certified pharmaceutical impurity reference standard with the molecular formula C15H14ClNO2SHCl and a molecular weight of 344.25 g/mol.

Clopidogrel Impurity 77 (C15H14ClNO2SHCl) 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. 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.

CATO manufactures Clopidogrel Impurity 77 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
