Chemical Structure
Description
Based on its molecular formula C8H12O7S, Oseltamivir Impurity 160 contains a carbohydrate-derived structure, a sulfone group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 252.24 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 160 (CAS CATO-C4X-1720160) is a certified pharmaceutical impurity reference standard with the molecular formula C8H12O7S and a molecular weight of 252.24 g/mol.
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
