Ceftiofur hydrochloride

About Ceftiofur hydrochloride

Ceftiofur hydrochloride is a high-purity reference standard of Ceftiofur carrying the CAS registry number 103980-44-5. Its molecular formula is C19H18ClN5O7S3 and its molecular weight is 560.0 g/mol. Common synonyms include Ceftiofur HCl and Ceftiofur monohydrochloride.

It is supplied as a solid. Store the standard in its sealed vial, protected from light and moisture, and follow the storage condition printed on the COA. The GHS classification uses the signal word “Danger”, so appropriate gloves, eye protection and ventilation are recommended.

Laboratories use this Ceftiofur 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.
