| | Dichlorprop Chemical Properties |
| | 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 | Dichloroprop is a herbicide used for the post-emergence control of annual and perennial broad-leaved weeds and some brush species. | | 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. |
