Oseltamivir

About Oseltamivir

Oseltamivir is a high-purity reference standard of Oseltamivir carrying the CAS registry number 196618-13-0. With the molecular formula C16H28N2O4, it has a molar mass of 312.4 g/mol. The IUPAC name is ethyl (3R,4R,5S)-4-acetamido-5-amino-3-pentan-3-yloxycyclohexene-1-carboxylate. Alternative names: (-)-Oseltamivir and Ebilfumin.

It is supplied as a solid. Keep the vial tightly closed, protected from light and humidity, at the temperature stated on the Certificate of Analysis. Good laboratory practice and suitable PPE are recommended during handling.

As a reference sample of Oseltamivir, it is used for identification, assay and impurity-profiling work during analytical method development, validation (AMV) and routine QC. Buyers come mainly from pharmaceutical manufacturing and academic and industrial research.

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