Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 487.37 g/mol gives Sofosbuvir Impurity 62 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Sofosbuvir Impurity 62 (CAS CATO-C4X-105262) is a certified pharmaceutical impurity reference standard with the molecular formula C19H23FN3O9P and a molecular weight of 487.37 g/mol.
Based on its molecular formula C19H23FN3O9P, Sofosbuvir Impurity 62 contains a flavonoid core, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 487.37 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
