Uses
2-(Trifluoromethyl)benzoic Acid is used in biochemical genetics studies such as Plasmid-encoded phthalate catabolic pathway in Arthrobacter keyseri 12B.
Chemical Properties
slightly yellow to yellow-brown crystalline powder
Uses
2-(Trifluoromethyl)benzoic acid was used in the synthesis of 1,3,4-oxadiazole derivatives containing 2-fluoro-4-methoxy moiety. It was also used to investigate the binding of 2-pyridinone and amino acid derivative as ligands with chaperones PapD and FimC by surface plasmon resonance and
1HNMR spectroscopy.

Definition
ChEBI: A benzoic acid carrying a trifluoromethyl substituent at the 2-position.
Synthesis
In a 5L stainless steel high-pressure reactor equipped with a mixer and a thermometer, the temperature was lowered to below 5C, hydrogen fluoride and 2-trichloromethyl dichlorobenzyl were added sequentially and the mass ratio of the two was 0.2:1, and then the catalyst perfluorooctane sulfonyl fluoride was added, and the mass ratio of 2-trichloromethyl dichlorobenzyl to the catalyst was 1:0.001, and the reaction pressure was controlled to be 2.5-2.8MPa for 4 hours. The temperature was raised to 80-90C, and the reaction pressure was controlled at 2.5-2.8 MPa for 4 hours. Sampling, GC detection, the intermediate product 2-difluoromonochloromethyl dichlorobenzyl content of 0.3%. At the end of the reaction, the excess hydrogen fluoride was removed by nitrogen purging, and neutralized with aqueous potassium carbonate to pH=6-7. After standing, the product 2-trifluoromethyl dichlorobenzyl chloride was isolated with 96.6% content and 94.1% yield.
The fluorination reaction product 2-trifluoromethyl dichlorobenzyl and nitric acid were reacted to obtain the target compound 2-trifluoromethyl benzoic acid after acid hydrolysis and oxidation reaction.
