3-Quinolinecarboxylic acid, 7-chloro-1-ethyl-6-fluoro-1,4-dihydro-4-oxo-,ethyl ester

Description:

3-Quinolinecarboxylic acid, 7-chloro-1-ethyl-6-fluoro-1,4-dihydro-4-oxo-, ethyl ester, identified by CAS number 70458-94-5, is a chemical compound that belongs to the class of quinoline derivatives. This substance features a quinoline ring structure, which is a bicyclic compound composed of a benzene ring fused to a pyridine ring. The presence of a carboxylic acid functional group indicates potential acidity, while the ethyl ester moiety suggests it can undergo hydrolysis to release ethanol. The chloro and fluoro substituents on the quinoline ring can influence the compound's reactivity and biological activity, potentially enhancing its pharmacological properties. The dihydro-4-oxo structure indicates that it may exhibit specific stereochemistry, which can be crucial for its interaction with biological targets. Overall, this compound may have applications in medicinal chemistry, particularly in the development of pharmaceuticals, owing to its unique structural features and functional groups.
