Chemical Structure
Description
The occurrence of Clopidogrel Impurity 70 is closely related to sulfur-containing functionality, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Clopidogrel Impurity 70 (CAS 13679-64-6), a pharmacopoeial impurity reference standard (molecular formula C6H6S, MW 110.18 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C6H6S, Clopidogrel Impurity 70 contains sulfur-containing functionality, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 110.18 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
