Chemical Structure

Clopidogrel Impurity 113 CAS 16694-46-5 chemical structure

Description

The molecular framework of Clopidogrel Impurity 113 (C3H7NOHCl) is characterized by an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Clopidogrel Impurity 113 (CAS 16694-46-5) is a certified pharmaceutical impurity reference standard with the molecular formula C3H7NOHCl and a molecular weight of 109.55 g/mol.

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.

CATO manufactures Clopidogrel Impurity 113 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.
