2-([1,1'-Biphenyl]-4-yl)-4-oxo-1,4-dihydroquinoline-8-carboxylic acid CAS 655222-78-9

Description

Based on its molecular formula C22H15NO3, 2-([1,1'-Biphenyl]-4-yl)-4-oxo-1,4-dihydroquinoline-8-carboxylic acid contains a steroid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 341.36 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
