Specifications | MSDS | Literature and Reviews


6-Fluoro-4-hydroxy-2-(trifluoromethyl)quinoline (CAS number 31009-34-4) is a derivative of quinoline, substituted with trifluoromethyl, hydroxyl and fluoride groups. 6-Fluoro-4-hydroxy-2-(trifluoromethyl)quinoline can exist in a tautomeric form, known as quinolone, where the hydroxy group becomes a ketone and the imine changes to an amine. 6-Fluoro-4-hydroxy-2-(trifluoromethyl)quinoline serves as a precursor for synthesising thioquinolines, which are used to develop non-cytotoxic, potent and selective antitubercular agents. The thiolation reaction is carried out using phosphorus pentasulfide in pyridine.

The tautomer of 6-fluoro-4-hydroxy-2-(trifluoromethyl)quinoline

Furthermore, the hydroxyl group in 6-fluoro-4-hydroxy-2-(trifluoromethyl)quinoline can undergo nucleophilic substitution to synthesis antiplasmodial agents for the treatment of malaria.
