Chemical Structure
Description
Clopidogrel Impurity 122 (CAS CATO-C4X-1029122) is a certified pharmaceutical impurity reference standard with the molecular formula C16H15ClNO2SO4P and a molecular weight of 415.78 g/mol.
Structurally, Clopidogrel Impurity 122 (C16H15ClNO2SO4P) contains a flavonoid core, an amide group, a sulfone group, a phosphate ester group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 9.5, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 415.78 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 122 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.
