Clopidogrel Sulfonated Impurity CAS 2173294-69-2

Description

The occurrence of Clopidogrel Sulfonated Impurity is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Clopidogrel Sulfonated Impurity (CAS 2173294-69-2), a pharmacopoeial impurity reference standard (molecular formula C16H16ClNO5S2, MW 401.88 g/mol) used for the identification and quantification of trace impurities in APIs.

Clopidogrel Sulfonated Impurity (C16H16ClNO5S2) contains a flavonoid core, an amide group, a sulfone 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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 Sulfonated Impurity 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.
