white to light yellow crystal powder
Uses
4-(Trifluoromethoxy)benzoic Acid is a substituted benzoic acid used in the preparation of a various biologically active compounds such as antifungal and antimalarial agents.
General Description
Kinetics of internal acyl migration and hydrolysis of the synthetic β-1-
O-acyl-D-glucopyranuronates of 2-, 3-, and 4-(trifluoromethyl)benzoic acids in phosphate buffer was studied.
Synthesis
Synthesis of 4-(trifluoromethoxy)benzoic acid: 4-(trifluoromethoxy)benzonitrile (4 g, 21.4 mmol) was dissolved in acetic acid (12 mL), and water (12 mL) and concentrated sulfuric acid (12 mL) were added sequentially. The reaction mixture was stirred and reacted at 120 °C overnight. Upon completion of the reaction, water (100 mL) was added to the mixture and the aqueous phase was extracted with ethyl acetate (3 x 100 mL). The organic phases were combined, dried with anhydrous sodium sulfate and concentrated under reduced pressure to give the title compound 4-(trifluoromethoxy)benzoic acid (4.8 g, 98% yield) as a white solid.
