Clopidogrel EP Impurity E (R-Isomer) CAS 444728-15-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Clopidogrel EP Impurity E (R-Isomer).

CATO supplies Clopidogrel EP Impurity E (R-Isomer) (CAS 444728-15-8), a pharmacopoeial impurity reference standard (molecular formula C15H15ClN2OS, MW 306.81 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C15H15ClN2OS, Clopidogrel EP Impurity E (R-Isomer) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 306.81 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

CATO manufactures Clopidogrel EP Impurity E (R-Isomer) 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.
