About Carbutamide

Listed under CAS 339-43-5, Carbutamide is an API reference standard available from Vaqora Chemicals. Its molecular formula is C11H17N3O3S and its molecular weight is 271.34 g/mol. The IUPAC name is 1-(4-aminophenyl)sulfonyl-3-butylurea. Alternative names: Glybutamide and Invenol.

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 the parent drug substance, 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.

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