About Diquat dibromide

Listed under CAS 85-00-7, Diquat dibromide is a high-purity reference standard of Allopurinol available from Vaqora Chemicals. Its molecular formula is C12H12Br2N2 and its molecular weight is 344.04 g/mol. Its systematic (IUPAC) name is 7,10-diazoniatricyclo[8.4.0.02,7]tetradeca-1(14),2,4,6,10,12-hexaene dibromide. Alternative names: Aquacide and Preeglone.

It is supplied as a solid. Store the standard in its sealed vial, protected from light and moisture, and follow the storage condition printed on the COA. Under GHS it is labelled “Danger”, so handle it with suitable PPE and consult the SDS.

As a reference sample of Allopurinol, 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.

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