About Mesna

Mesna is a high-purity reference standard of Mesna carrying the CAS registry number 19767-45-4. Formula C2H5NaO3S2, molecular weight 164.18 g/mol. Systematically, it is named sodium 2-sulfanylethanesulfonate. It is also known as Sodium 2-mercaptoethanesulfonate or 2-Mercaptoethanesulfonic acid sodium salt.

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 “Danger”, so appropriate gloves, eye protection and ventilation are recommended.

As a reference sample of Mesna, it is used for identification, assay and impurity-profiling work during analytical method development, validation (AMV) and routine QC. It is used across pharmaceutical manufacturing and academic and industrial research.

Vaqora Chemicals supplies Mesna in 10 mg, 25 mg, 50 mg and 100 mg packs, each shipped with a Certificate of Analysis (COA), and exports worldwide.
