Description

ChEBI: The R- (active) enantiomer of dichlorprop. It is used as a herbicide for killing annual and broad leaf weeds.

(R)-dichlorprop is the R- (active) enantiomer of dichlorprop. It is used as a herbicide for killing annual and broad leaf weeds. It has a role as an agrochemical, an EC 1.11.1.6 (catalase) inhibitor, a synthetic auxin and a phenoxy herbicide. It is a conjugate acid of a (R)-dichlorprop(1-). It is an enantiomer of a (S)-dichlorprop.

(+)-Dichlorprop Use and Manufacturing

Methods of Manufacturing

Mix L-2-chloropropionic acid methyl ester ([α]20D-25.2 o) with methanol and 33% aqueous sodium hydroxide solution below 40°C, and add to 2, 4-dichlorophenol and hydroxide at 90°C In the mixed solution of sodium and water, heat at 90 ℃ for 1h to obtain 2, 4-D sodium propionate. D-isomer >87%. High 2, 4-D propionic acid can generate various esters. The molecular formula of dichlorprop-p-isobutyl is C13H16Cl2O3; the molecular formula of dichlorprop-p-dimethylammonium is C11H15C潼NO3, CANO. [104786-87-0].
