About Clopidol

Clopidol (CAS 2971-90-6) is an API reference standard offered by Vaqora Chemicals. With the molecular formula C7H7Cl2NO, it has a molar mass of 192.04 g/mol. Systematically, it is named 3,5-dichloro-2,6-dimethyl-1H-pyridin-4-one. Common synonyms include Meticlorpindol and Coccidiostat C.

It is supplied as a solid. Reference materials should be stored sealed and away from light and moisture, as specified on the accompanying COA. Under GHS it is labelled “Warning”, so handle it with suitable PPE and consult the SDS.

As a reference sample of the parent drug substance, it is used for identification, assay and impurity-profiling work during analytical method development, validation (AMV) and routine QC. Typical end-use sectors are pharmaceutical manufacturing and academic and industrial research.

Standard pack sizes are 10 mg, 25 mg, 50 mg and 100 mg, and every batch ships with a Certificate of Analysis (COA) and we export worldwide.
