Usage

Uses

Different sources of media describe the Uses of 1689-99-2 differently. You can refer to the following data:
1. Herbicide.
2. Selective contact foliage-applied herbicide used to control many broad-leaved weeds such as bindweed, chickweed and Veronica spp. in cereals.

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

Notclassified

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?

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).
