2,4-Dichlorophenoxyacetic acid is an organic compound with the chemical formula Cl 2 C 6 H 3 OCH 2 CO 2 H.It is usually referred to by its ISO common name 2,4-D. [4] It is a systemic herbicide that kills most broadleaf weeds by causing uncontrolled growth, but most grasses such as cereals, lawn turf, and grassland are relatively unaffected.
The best known phenoxy herbicides are (4-chloro-2-methylphenoxy)acetic acid , 2,4-dichlorophenoxyacetic acid (2,4-D) and 2,4,5-trichlorophenoxyacetic acid (2,4,5-T). [2] Analogues of each of these three compounds, with an extra methyl group attached next to the carboxylic acid, were subsequently commercialised as mecoprop, dichlorprop and fenoprop
3,4-Dichlorophenol 3,5-Dichlorophenol Dichlorophenols are used as intermediates in the manufacture of more complex chemical compounds, including the common herbicide 2,4-dichlorophenoxyacetic acid (2,4-D).
2,4-Dichlorophenol (2,4-DCP) is a chlorinated derivative of phenol with the molecular formula Cl 2 C 6 H 3 OH. It is a white solid that is mildly acidic (pK a = 7.9). It is produced on a large scale as a precursor to the herbicide 2,4-dichlorophenoxyacetic acid (2,4-D).
2,4-DB or 4-(2,4-dichlorophenoxy)butyric acid is a selective systemic phenoxy herbicide used to control many annual and perennial broad-leaf weeds in alfalfa, peanuts, soybeans, and other crops. Its active metabolite , 2,4-D , inhibits growth at the tips of stems and roots.

2,4,5-Trichlorophenol (TCP) is an organochloride with the molecular formula C 6 H 3 Cl 3 O.It has been used as a fungicide and herbicide. [2] Precursor chemical used in the production of 2,4,5-Trichlorophenoxyacetic acid (2,4,5-T) and hexachlorophene involves the intermediate production of 2,4,5-trichlorophenol (TCP) and the formation of 2,3,7,8-Tetrachlorodibenzodioxin (TCDD, commonly ...
