Benznidazole

About Benznidazole

Benznidazole is an API reference standard carrying the CAS registry number 22994-85-0. Its molecular formula is C12H12N4O3 and its molecular weight is 260.25 g/mol. Systematically, it is named N-benzyl-2-(2-nitroimidazol-1-yl)acetamide. It is also known as Benznidazol or benzonidazol.

It is supplied as a solid. Reference materials should be stored sealed and away from light and moisture, as specified on the accompanying COA. It carries the GHS signal word “Warning” with 3 hazard statements. Review the Safety Data Sheet before use.

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.
