Pendimethalin Chemical Properties,Uses,Production
Chemical Properties
Brown Solid
Uses
Herbicide used to control the spread of weedgrass.
Definition
ChEBI: A member of the class of substituted anilines that is N-(pentan-3-yl)aniline bearing two additional nitro substituents at positions 2 and 6 as well as two methyl substituents at positions 3 and 4. A herbicide used to control most annual rasses and many annual broad-leaved weeds.
General Description
Orange-yellow crystals. Non corrosive. Used as an herbicide.
Air & Water Reactions
Insoluble in water.
Reactivity Profile
A dinitroaniline derivative.
Agricultural Uses
Herbicide: Pendimethalin is a selective pre-emergence and post-emergence herbicide used on various agricultural and non-agricultural sites to control broadleaf weeds and grassy weeds in crops such as apricot, carrot, cherry, corn, cotton, fig, garbanzos, garlic, olive, onion, nectarine, peach, pear, pecan, plum, rice and prune, and noncrop areas. It is applied to soil preplant, pre-emergence, and post-emergence with ground and aerial equipment.

Potential Exposure
Pendimethalin is a selective preemergence and postemergence 2,6-dinitroaniline herbicide used on various agricultural and non-agricultural sites to control broadleaf weeds and grassy weeds in crops such as apricot, carrot, cherry, corn, cotton, fig, garbanzos, garlic, olive, onion, nectarine, peach, pear, pecan, plum, rice and prune, and noncrop areas. It is applied to soil preplant, pre-emergence, and postemergence with ground and aerial equipment.
Metabolic pathway
Irradiation of pendimethalin in methanol yields, in addition to the minor dealkylated product, the major products 2-amino-6-nitro-N-(1-ethylpropyl)-3,4-xylidine and 2-nitroso-6-nitro-3,4-xylidine. Pendimethalin degrades rapidly through reductive cyclization of the amino group and adjacent N-ethylpropyl to give a cyclized benzimidazole product. The photodecomposition of pendimethalin involves oxidative dealkylation, nitro reduction, and cyclization. By soil bacteria, pendimethalin degrades through different pathways from the photodegradation reaction, resulting in benzimidazole and hydroxylated products of the N-alkyl and xylyl methyl groups. The major metabolic routes of pendimethalin by rats involves hydroxylation of the 4-methyl and the N-ethyl group, oxidation of these alkyl groups to carboxylic acids, nitro reduction, cyclization, and conjugation in the urine and the tissues. Products of cyclization reactions giving methylbenzimidazole-carboxylic acids are unique metabolites to the liver and kidney.
Shipping
UN3077 Environmentally hazardous substances, solid, n.o.s., Hazard class: 9; Labels: 9-Miscellaneous hazardous material, Technical Name Required.
Incompatibilities
Reacts with oxidizers, acids and alkaline materials. Contact with strong oxidizers may cause fire and explosions.
Waste Disposal
It is the responsibility of chemical waste generators to determine if a discarded chemical is classified as a hazardous waste. See 40 CFR Parts 261.3 for United States Environmental Protection Agency guidelines for the classification determination. Additionally, in order to ensure complete and accurate classification, waste generators must consult state and local hazardous waste regulations. Organic pesticides, whether of botanical or synthetic origin, can be destroyed by incineration equipped with scrubbers to remove acid wastes.
