The reagent was used in trifluoromethylation of a thiophenolate. S-(trifluoromethyl)dibenzothiophenium tetrafluoroborate is a commercially available and known trifluoromethylation reagent based on the same principle first documented in 1990. [64] [65] In this type of compound sulfur has been replaced by oxygen, selenium and tellurium.
Fluridone's main action to disrupt photosynthesis in plants is by preventing the secretion of abscisic acid. [8] As higher eukaryotes, such as humans, also rely on an abscisic acid pathway [9] to create inflammation in normal physiological processes, fluridone could be investigated as being of interest in the development of anti-inflammatory agents.
Sulfoxaflor is used as a systemic insecticide. Trifluralin, as with several dinitritroaniline herbicides, is a trifluoromethyl herbicide. Fluazifop is another, a phenoxy herbicide. The trifluoromethyl group can also be added to change the solubility of molecules containing other groups of interest.
Two other isomers are also known: 2-trifluoromethylbenzaldehyde and 3-trifluoromethylbenzaldehyde. These compounds are derivatives of benzaldehyde with trifluoromethyl substituents. The CF 3 group enhances the electrophilicity of the formyl group and provides a label for analysis by fluorine-19 nuclear magnetic resonance spectroscopy.
It is unclear why trifluralin's exotic 4-trifluoromethyl was tested so early (1960), before more common candidates such as fluoro, bromo, or iodo. [7] By 1968, trifluralin was internationally available, including Australia and New Zealand, [6] and trifluralin was the 5th most used herbicide in the US, at 22,960,000 pounds (10,410 t) by 1974.

One lampricide is used in the headwaters of Lake Champlain and the Great Lakes to control the sea lamprey (Petromyzon marinus), an invasive species to these lakes. [1] TFM (3-trifluoromethyl-4-nitrophenol) is the main chemical used for this purpose. As it is hydrophobic, it passes through biological membranes.
Trifluoroacetaldehyde, trifluoroethanal, or fluoral, [2] is a fluorinated derivative of acetaldehyde with the formula CF 3 CHO.It is a gas at room temperature. Fluoral is used to introduce trifluoromethyl groups into organic compounds.
Fipronil (IUPAC name 5-amino-1-[2,6-dichloro-4-(trifluoromethyl)phenyl]-4-(trifluoromethylsulfinyl)pyrazole-3-carbonitrile [1]) is a white, solid powder with a moldy odor. It is degraded slightly by sunlight, stable at normal temperatures for one year, and is not stable in presence of metal ions .
