Biological Activity

Oseltamivir is an antiviral drug, which may slow the spread of influenza (flu) virus between cells in the body by stopping the virus from chemically cutting ties with its host cell.


Solubility (25°C)* In vitro DMSO 2 mg/mL (4.87 mM)

Ethanol <1 mg/mL (<1 mM)
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Adooq tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
