Synthesis method
By2,4-Dichlorophenol It is obtained by condensation of sodium salt and α-chloropropionic acid. This product is a mixture of two optical isomers, but only the right-handed isomer has biological activity.
Purpose
Inject special post-emergent herbicide. Effective in controlling Polygonum weeds in cereal fields.
