[Chemical Properties]

Cis-(±)-2,2-dimethyl-3-(2-methylprop-1-enyl)cyclopropanecarboxylic acid is white crystal, mp113~116℃, insoluble in water, soluble in benzene, toluene, ether and other solvents.
[Uses]

(±) Cis chrysanthemic acid is an intermediate of pyrethroid and can be used to prepare deltamethrin.
[Definition]

ChEBI: (+)-cis-chrysanthemic acid is a cis-chrysanthemic acid. It is an enantiomer of a (-)-cis-chrysanthemic acid.
[Synthesis]

Its preparation method is to dissolve (±) cis-chrysanthemic acid in sodium hydroxide solution, and pass carbon dioxide at room temperature. In the solution, after filtration to remove trans chrysanthemic acid, the remaining liquid is acidified and recrystallized to obtain (±) cis chrysanthemic acid.
