Chemical Structure
Description
Based on its molecular formula C13H12FNO3, Ethyl 6-fluoro-8-methyl-4-oxo-1,4-dihydroquinoline-3-carboxylate 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 249.24 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).
