34-Difluorobenzonitrile CAS No 64248-62-0

Application

3,4-Difluorobenzonitrile is used in analytical chemistry as well as the pharmaceutical, agrochemical, and specialty chemical industries. By using the chemical as a reference standard for chromatographic analysis, researchers may precisely detect and measure the amount of 3,4-Difluorobenzonitrile present in a variety of substances.

An essential step in the production of the selective herbicide cyhalofopbutyl is 3,4-Difluorobenzonitrile. Through amidation, dehydration, and fluorination, 3,4-dichlorobenzoyl chloride is converted into 3,4-Difluorobenzonitrile. The product content is 99.0% and the overall yield is 39.8%. For industrialization, this is the most promising synthetic approach.

A wide range of medications, dyes, and liquid crystal materials can be made using 3,4-Difluorobenzonitrile as an intermediary. It is also a crucial step for cyhalofop-ate, a selective herbicide. Cyhalofop-ethyl is a rice herbicide that is selective. For both transplanted and direct-seeded rice, it is very safe. It is acknowledged as a superior rice herbicide on a global scale. There is a considerable market need for 3,4-difluorobenzonitrile due to the quick development of cyhalofop-methyl.
