BUTRALIN Usage And Synthesis

Chemical Properties

Butralin is a yellow
orange crystalline solid or liquid. Commercial product is available as an emulsifiable concentrate.

Uses

Herbicide.

Definition

ChEBI: Butralin is a C-nitro compound.

Agricultural Uses

Herbicide; plant growth regulator: Not approved for use in EU countries. Actively registered for use in the U.S. Butralin is used as a plant growth regulator on tobacco after the tobacco is topped. All tobacco is topped to stimulate desirable chemical and physical characteristics but it also stimulates the growth of suckers. All uses on food crops were canceled in January, 1991, and all uses on turf and ornamental grasses were voluntarily canceled in March, 1997. It may be used on food crops, broadleaf weeds and ornamentals in some countries. Butralin has been found effective in destroying opium poppy crops.

Potential Exposure

2,6-Dinitroaniline herbicide; plant growth regulator. Butralin is used as a plant grow regulator on tobacco after the tobacco is topped. All tobacco is topped to stimulate desirable chemical and physical characteristics but also stimulates the growth of suckers. It may be used on food crops, broad leaf weeds and ornamentals in some countries. Butralin is been found effective in destroying opium poppy crops.

Actively registered for use in the United States Not approved for use in EU countrieS

Shipping

UN1596 Dinotoanilines, Hazard Class: 6.1; Labels: 6.1—Poisonous materials. UN3082 Environmentally hazardous substances, liquid, n.o.s., Hazard class: 9; Labels: 9—Miscellaneous hazardous material, Technical Name Required. UN3077 Environmentally hazardous substances, solid, n.o.s., Hazard class: 9; Labels: 9—Miscellaneous hazardous material, Technical Name Required

Incompatibilities

Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides

Waste Disposal

Do not discharge into drains or sewers. Dispose of waste material as hazardous waste using a licensed disposal contractor to an approved landfill. Contact a licensed disposal facility about surplus andnonrecyclable solutions. Burn in a chemical incinerator equipped with an afterburner and scrubber. Extra care must be exercised as the material in an organic solvent is highly flammable. Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Incineration with effluent gas scrubbing is recommended. Containers must be disposed of properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office. Do not reuse container.
