Ceftizoxime

About Ceftizoxime

Ceftizoxime is a high-purity reference standard of Ceftizoxime carrying the CAS registry number 68401-81-0. Its molecular formula is C13H13N5O5S2 and its molecular weight is 383.4 g/mol. Alternative names: FK-749 and ceftizoximum alapivoxilum.

It is supplied as a solid. Reference materials should be stored sealed and away from light and moisture, as specified on the accompanying COA. Under GHS it is labelled “Danger”, so handle it with suitable PPE and consult the SDS.

Laboratories use this Ceftizoxime standard for identity and assay testing, system suitability checks and method validation supporting ANDA and DMF filings. Buyers come mainly from 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.
