Application

4-(Trifluoromethyl)benzoic acid was used in the synthesis of salicylanilide 4-(trifluoromethyl)benzoates via N,N′-dicyclohexylcarbodiimide coupling in dry N,N-dimethylformamide. It was used as internal standard during the ultra trace analysis of fluorinated aromatic carboxylic acids by GC/MS method.

This work shows that high resolution magic angle spinning (HR-MAS) can be used to elucidate ligand-receptor binding phenomena for mass-limited samples in liquid solution. With respect to conventional 5mm liquid-state NMR probe heads, HR-MAS allows for a considerable reduction (about

Enzymes of the p-cymene pathway in Pseudomonas putida strains cometabolized the intermediate analogue 4-trifluoromethyl(TFM)benzoate. Three products, 4-TFM-2,3-dihydro-2,3-dihydroxybenzoate, 4-TFM-2,3-dihydroxybenzoate and 2-hydroxy-6-oxo-7,7,7-trifluorohepta-2,4-dienoate (7-TFHOD) were identified chemically and by spectroscopic properties. Certain TFM-substituted analogue metabolites of the p-cymene pathway were transformed at drastically
