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.
Dimethylamine is an organic compound with the formula (CH 3) 2 NH. This secondary amine is a colorless, flammable gas with an ammonia-like odor. Dimethylamine is commonly encountered commercially as a solution in water at concentrations up to around 40%. An estimated 270,000 tons were produced in 2005. [5]
Today, only R-dichlorprop (also called dichlorprop-p or 2,4-DP-p) and its derivatives are sold as pesticides in the United States. Dichlorprop is a carboxylic acid, and like related herbicides with free acid groups, it is often sold as a salt or ester. Currently, the 2-ethylhexyl ester is used commercially. The butoxyethyl and isooctyl esters ...
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.
DOM is a chiral molecule, and R-(−)-DOM is the more active enantiomer, functioning as a potent agonist of the serotonin 5-HT family of receptors, mainly of the 5-HT2 subtype. [5] The drug is inactive as a human trace amine-associated receptor 1 (TAAR1) agonist but is an agonist of the rhesus monkey TAAR1.
Picloram is a systemic herbicide used for general woody plant control. It also controls a wide range of broad-leaved weeds, but most grasses are resistant. [3] A chlorinated derivative of picolinic acid, picloram is in the pyridine family of herbicides.
4-Aminodiphenylamine is a diphenylamine with an additional amine substituent. This dimer of aniline has various industrial uses, including as a hair dye ingredient, but also has raised concerns about toxicity by skin contact. [1] It is also a starting material for the synthesis of 6PPD, an antiozonant for various rubber products. [2]
C 6 H 4 (CO) 2 NH + RX + NaOH → C 6 H 4 (CO) 2 NR + NaX + H 2 O. The amine is commonly liberated using hydrazine: C 6 H 4 (CO) 2 NR + N 2 H 4 → C 6 H 4 (CO) 2 N 2 H 2 + RNH 2. Dimethylamine can also be used. [5] Some examples of phthalimide drugs include thalidomide, amphotalide, taltrimide, talmetoprim, and apremilast.
