About Pyrvinium Pamoate

Vaqora Chemicals supplies Pyrvinium Pamoate, a high-purity reference standard of Pyrvinium registered under CAS number 3546-41-6. Its molecular formula is C75H70N6O6 and its molecular weight is 1151.4 g/mol. Alternative names: Pyrvinium (as embonate) and Alnoxin.

It is supplied as a solid. Reference materials should be stored sealed and away from light and moisture, as specified on the accompanying COA. The GHS classification uses the signal word “Warning”, so appropriate gloves, eye protection and ventilation are recommended.

As a reference sample of Pyrvinium, 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.
