Chemical Structure
Description
Based on its molecular formula C8H10FN3O4, Emtricitabine impurity 49 contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 231.18 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).
Emtricitabine impurity 49 (CAS CATO-C4X-123249) is a certified pharmaceutical impurity reference standard with the molecular formula C8H10FN3O4 and a molecular weight of 231.18 g/mol.
