About Flumazenil

Flumazenil (CAS 78755-81-4) is a high-purity reference standard of Flumazenil offered by Vaqora Chemicals. Its molecular formula is C15H14FN3O3 and its molecular weight is 303.29 g/mol. Its systematic (IUPAC) name is ethyl 8-fluoro-5-methyl-6-oxo-4H-imidazo[1,5-a][1,4]benzodiazepine-3-carboxylate. Alternative names: Flumazenil (WSM) and Anexate.

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.

Laboratories use this Flumazenil standard for identity and assay testing, system suitability checks and method validation supporting ANDA and DMF filings. Our customers for this product work in pharmaceutical manufacturing and academic and industrial research.

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