About Quinidine sulphate

Listed under CAS 50-54-4, Quinidine sulphate is a high-purity reference standard of Quinidine available from Vaqora Chemicals. Its molecular formula is C40H50N4O8S and its molecular weight is 746.9 g/mol. It is also known as Quinidine sulfate or Quinidine sulfate anhydrous.

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 Quinidine, 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.

We offer Quinidine sulphate in 10 mg, 25 mg, 50 mg and 100 mg packs with a batch-specific COA, and ship to customers worldwide.
