Chemical Structure
Description
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 process- or degradation-related impurity, Clopidogrel Impurity 104 (CAS CATO-C4X-1029104, C15H16ClNO2S) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Structurally, Clopidogrel Impurity 104 (C15H16ClNO2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 309.81 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO manufactures Clopidogrel Impurity 104 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.
