About Divalproex sodium

Vaqora Chemicals supplies Divalproex sodium, a high-purity reference standard of Divalproex registered under CAS number 76584-70-8. Formula C16H31NaO4, molecular weight 310.4 g/mol. Common synonyms include Valdisoval and Valproate semisodium.

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.

Laboratories use this Divalproex standard for identity and assay testing, system suitability checks and method validation supporting ANDA and DMF filings. Typical end-use sectors are 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.
