| Physical and Chemical Properties | Chemical properties Z-cis-chlorofluorochrysanthemum chloride is a colorless liquid with a pungent odor, which decomposes in water and reacts with alcohol to form the corresponding ester, which is soluble in organic solvents such as benzene and toluene. |
| Use | Uses Z-cis-chlorofluorochracyl chloride is an intermediate for the preparation of high-efficiency cyhalothrin (kungfu permethrin), heptefluthrin, bifenthrin and other pyrethroids. |
| Raw Materials | Thionyl chloride Z-(1R,S)-cis-2,2-dimethyl-3-(2,2-chloro-3,3,3-trifluoro-1-propenyl)cyclopropanecarboxylic acid |
The preparation method is that Z-cis-chlorofluorochrysanthemum acid reacts with thionyl chloride in toluene to form the corresponding Z-cis-chlorofluorochrysanthemum chloride.
