About Primidone

Primidone (CAS 125-33-7) is a high-purity reference standard of Primidone offered by Vaqora Chemicals. With the molecular formula C12H14N2O2, it has a molar mass of 218.25 g/mol. The IUPAC name is 5-ethyl-5-phenyl-1,3-diazinane-4,6-dione. Alternative names: Primaclone and Mysoline.

It is supplied as a solid. Reference materials should be stored sealed and away from light and moisture, as specified on the accompanying COA. It carries the GHS signal word “Danger” with 3 hazard statements. Review the Safety Data Sheet before use.

As a reference sample of Primidone, it is used for identification, assay and impurity-profiling work during analytical method development, validation (AMV) and routine QC. Buyers come mainly from 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.
