About Sulfameter

Sulfameter is an API reference standard carrying the CAS registry number 651-06-9. Formula C11H12N4O3S, molecular weight 280.31 g/mol. The IUPAC name is 4-amino-N-(5-methoxypyrimidin-2-yl)benzenesulfonamide. Common synonyms include Sulfamethoxydiazine and Sulfametoxydiazine.

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

Laboratories use this the parent drug substance 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.
