Chemical Structure
Description
CATO supplies Clopidogrel Impurity 36 HCl (CAS 1346605-15-9 (free base)), a pharmacopoeial impurity reference standard (molecular formula C16H18ClNO2SHCl, MW 360.29 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C16H18ClNO2SHCl, Clopidogrel Impurity 36 HCl contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 360.29 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
As a certified reference material (CRM), Clopidogrel Impurity 36 HCl 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.
