storage method

none

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.
