2,3-Dichloro-5-(trifluoromethyl)pyridine Use and Manufacturing

Methods of Manufacturing

Its preparation method uses 3-methylpyridine as raw material in the presence of a catalyst to produce this product through chlorination and fluorination. It can also be chlorinated on the ring with 2-chloro-5-trichloromethylpyridine to obtain 2, 3-dichloro-5-trichloromethylpyridine, which is then fluorinated with hydrogen fluoride to obtain the product.

Uses

2,3-Dichloro-5-trifluoromethylpyridine is an intermediate of the insecticides diflubenzuron and flufenoxuron, and can also be used to synthesize the herbicide flupiroxol (capped).
