Dichlorprop Usage And Synthesis

Chemical Properties

2,4-DP is a combustible, colorless to yellowish to tan crystalline solid with a faint phenolic odor

Uses

herbicide

Definition

ChEBI: An aromatic ether that is 2-hydroxypropanoic acid in which the hydroxy group at position 2 has been converted to its 2,4-dichlorophenyl ether.

General Description

Yellowish to colorless solid. Soluble in organic solvents. Used as an herbicide.

Reactivity Profile

Dichlorprop is an organic acid. Neutralizes bases in exothermic reactions.

Safety Profile

Suspected carcinogen. Poison by ingestion. Moderately toxic by skin contact. An experimental teratogen. Other experimental reproductive effects. Mutation data reported. A fumigant. When heated to decomposition it emits toxic fumes of Cl-.

Potential Exposure

A phenoxy herbicide

Environmental Fate

The average field half-life is 10 days. Microbial degradation and plant uptake account for the short half-life of dichlorprop. Losses due to leaching, photodegradation, and volatilization are minimal.

Metabolism

Chemical. Dichlorprop and its salts are very stable, but esters readily hydrolyze under acidic and basic conditions.
Plant. Degradation of the side chain of dichlorprop to form 2,4-dichlorophenol is most common. Dichlorprop may be conjugated to form glucosides, diglucosides, and to a limited extent triglucosides.
Soil. The degradation pathway of dichlorprop is similar in plants and soils, forming 2,4-dichlorophenol. Evidence indicates that some microbial communities preferentially degrade the R-enantiomer.

Shipping

UN3345 Phenoxyacetic acid derivative pesticide, solid, toxic, Hazard Class: 6.1; Labels: 6.1-Poisonous materials

Purification Methods

Crystallise 2,4-DP from MeOH. It is a plant growth substance, a herbicide and is TOXIC. The R(+)-and S(-)-enantiomers have m 124o (from *C6H6) and [] D ±35.2o (c 1, Me2CO). [Beilstein 6 H 189, 6 III 708, 6 IV 922-923.]

Toxicity evaluation

Mammalian Toxicity. Dichlorprop appears to be excreted unchanged in animals. The acute oral LD50s of dichlorprop in rat and mice are 825–1470 mg/kg and 400 mg/kg, respectively.

Incompatibilities

Dust may form explosive mixture with air. Contact with oxidizers may cause a fire and explosion hazard. The aqueous solution is a weak acid. Attacks many metals in presence of moisture. Compounds of the carboxyl group react with all bases, both inorganic and organic (i.e., amines) releasing substantial heat, water and a salt that may be harmful. Incompatible with arsenic compounds (releases hydrogen cyanide gas), diazo compounds, dithiocarbamates, isocyanates, mercaptans, nitrides, and sulfides (releasing heat, toxic and possibly flammable gases), thiosulfates and dithionites (releasing hydrogen sulfate and oxides of sulfur).

Waste Disposal

In accordance with 40CFR165, follow recommendations for the disposal of pesticides and pesticide containers. Must be disposed properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office.
