Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 234.08 g/mol gives Clopidogrel Impurity 75 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Clopidogrel Impurity 75 (CAS 1217999-35-3), a pharmacopoeial impurity reference standard (molecular formula C9H9Cl2NO2, MW 234.08 g/mol) used for the identification and quantification of trace impurities in APIs.
Clopidogrel Impurity 75 (C9H9Cl2NO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
CATO manufactures Clopidogrel Impurity 75 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.
