Clopidogrel EP Impurity A  is chemically (2S)-2-(2-chlorophenyl)-2-[6,7-dihydrothieno[3,2-c]pyridin-5(4H)-yl]acetic acid. It is also known as Clopidogrel USP Related Compound A. Clopidogrel EP Impurity A  is supplied with detailed characterization data compliant with regulatory guideline. Clopidogrel EP Impurity A  can be used for the analytical method development, method validation (AMV), Quality Controlled (QC) application for Abbreviated New Drug Application (ANDA) or during commercial production of Clopidogrel.

The product can be used as reference standards and further traceability against pharmacopeial standards (USP or EP) can be provided based on feasibility. SynZeal products are for analytical purpose only and not for human use.
