| Chemical Properties | Bromoxynil is a colorless to white crystallinesolid or tan powder. Odorless (pure). |
| Uses | Selective contact foliage-applied herbicide used to control many broad-leaved weedssuch as bindweed, chickweed and Veronica spp. in cereals. |
| Uses | Herbicide. |
| General Description | A solid. Used as a selective contact herbicide. |
| Reactivity Profile | Bromoxynil octanoate is an ester. Readily hydrolyzed to bromoxynil and octanoate at pH's exceeding 9. |
| Health Hazard | Highly toxic, may be fatal if inhaled, swallowed or absorbed through skin. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution. |
| Fire Hazard | Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Containers may explode when heated. Runoff may pollute waterways. |
| Flammability and Explosibility | Not classified |
| Agricultural Uses | Herbicide: A U.S. EPA restricted Use Pesticide (RUP).Herbicide used for alfalfa seedlings, barley, corn, flax,garlic, grasses, mint, oats, onions, popcorn, rye, sorghum,triticale, wheat. See also below. |
| Trade name | BROMINAL®-W; BUCTRIL®Bromoxynil octoate; NPH-1320® |
| Potential Exposure | Bromoxynil is a hydroxybenzonitrileherbicide used for postemergent control of broadleafweeds; on alfalfa, garlic, corn, sorghum, flax, cereals,turf and on pasture and rangelands. A United StatesEnvironmental Protection Agency RUP. |
| Environmental Fate | Chemical/Physical. Emits toxic fumes of nitrogen oxides and bromine when heatedto decomposition (Sax and Lewis, 1987). Hydrolyzes, especially at pH >9, to bromoxyniland octanoic acid (Hartley and Kidd, 1987; Worthing and Hance, 1991). |
| Shipping | UN2588 Pesticides, solid, toxic, Hazard Class:6.1; Labels: 6.1—Poisonous materials, Technical NameRequired. |
| Incompatibilities | A weak acid; keep away from bases andalkalies. React with boranes, alkalies, aliphatic amines,amides, nitric acid, sulfuric acid. Keep away from oxidizers(chlorates, nitrates, peroxides, permanganates, perchlorates,chlorine, bromine, fluorine, etc.) and strong acids. |
| Waste Disposal | Do not discharge into drainsor sewers. Dispose of waste material as hazardous wasteusing a licensed disposal contractor to an approved landfill.Incineration with effluent gas scrubbing is recommended.Consult with environmental regulatory agencies for guidanceon acceptable disposal practices. If allowed,Incineration with effluent gas scrubbing is recommended.Containers must be disposed of properly by followingpackage label directions or by contacting your local or federalenvironmental control agency, or by contacting yourregional EPA office. |
