Ertapenem Disodium

About Ertapenem Disodium

Ertapenem Disodium is a high-purity reference standard of Ertapenem carrying the CAS registry number 3017-69-4. Its molecular formula is C4H7Br and its molecular weight is 135.0 g/mol. Systematically, it is named 1-bromo-2-methylprop-1-ene. It is also known as 1-Bromo-2-methyl-1-propene or 1-Propene, 1-bromo-2-methyl-.

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

Laboratories use this Ertapenem standard for identity and assay testing, system suitability checks and method validation supporting ANDA and DMF filings. It is used across pharmaceutical manufacturing and academic and industrial research.

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