3-Fluoro-4-(trifluoromethyl)benzoic acid (CAS number 115754-21-7) is a benzoic acid derivative bearing a trifluoromethyl and a fluoride at 3- and 4-positions. The carboxylic acid group in 3-fluoro-4-(trifluoromethyl)benzoic acid can chelate with metal centers such as dysprosium, leading to pH tuneable magnetic organometallic clusters with slow magnetic relaxation.
3-Fluoro-4-(trifluoromethyl)benzoic acid has been extensively studied for active pharmaceutical ingredients (APIs). 3-Fluoro-4-(trifluoromethyl)benzoic acid serves as a crucial building block in the synthesis of potassium channel openers used for the treatment of epilepsy. The potassium channel openers are synthesized by condensation reactions involving 3-fluoro-4-(trifluoromethyl)benzoic acid and aminopyridine.
