Bromoxynil octanoate Usage And Synthesis

Chemical Properties

Bromoxynil is a colorless to white crystalline solid or tan powder. Odorless (pure).

Uses

Selective contact foliage-applied herbicide used to control many broad-leaved weeds such 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 hydroxybenzonitrile herbicide used for postemergent control of broadleaf weeds; on alfalfa, garlic, corn, sorghum, flax, cereals, turf and on pasture and rangelands. A United States Environmental Protection Agency RUP.

Environmental Fate

Chemical/Physical. Emits toxic fumes of nitrogen oxides and bromine when heated to decomposition (Sax and Lewis, 1987). Hydrolyzes, especially at pH >9, to bromoxynil and 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 Name Required.

Incompatibilities

A weak acid; keep away from bases and alkalies. 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 drains or sewers. Dispose of waste material as hazardous waste using a licensed disposal contractor to an approved landfill. Incineration with effluent gas scrubbing is recommended. Consult with environmental regulatory agencies for guidance on acceptable disposal practices. If allowed, 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.
