Product Description:

2,6-Difluorobenzonitrile is an organic compound featuring a benzonitrile core with fluorine substituents at the 2- and 6-positions. It is a white to off-white crystalline solid with a molecular formula of C7H3F2N. This compound is a key intermediate in the synthesis of various agrochemicals. Its primary industrial application is in the production of modern pyrethroid insecticides, such as cyhalothrin and cyfluthrin. The difluorobenzonitrile moiety is a crucial structural component that contributes to the insecticidal activity and photostability of these final products. It serves as a versatile building block for introducing the difluorophenyl group into target molecules. As a bifunctional synthon containing both a cyano group and fluorine atoms, it is also employed in organic synthesis for constructing more complex aromatic systems, particularly in pharmaceutical research. The cyano group can be further transformed into other functional groups like carboxylic acids or amidines, enhancing its utility as a synthetic intermediate.
