About Benzthiazide

Vaqora Chemicals supplies Benzthiazide, a high-purity reference standard of Benzthiazide registered under CAS number 91-33-8. Its molecular formula is C15H14ClN3O4S3 and its molecular weight is 431.9 g/mol. The IUPAC name is 3-(benzylsulfanylmethyl)-6-chloro-1,1-dioxo-4H-1lambda6,2,4-benzothiadiazine-7-sulfonamide. Alternative names: Benzothiazide and Fovane.

The product is provided 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 Benzthiazide 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.

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