Chemical Structure
Description
Based on its molecular formula C12H18O4, Oseltamivir Impurity 101 contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 226.27 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Oseltamivir Impurity 101 (CAS CATO-C4X-1720101) is a certified pharmaceutical impurity reference standard with the molecular formula C12H18O4 and a molecular weight of 226.27 g/mol.
