Description
Bromoxynil octanoate, also known as Bromoxynil, is a selective contact herbicide primarily used in agriculture. It is a solid substance that effectively controls various broad-leaved weeds, making it a valuable tool for maintaining crop health and yield.
Uses
Used in Agricultural Industry:
Bromoxynil octanoate is used as a herbicide for controlling many broad-leaved weeds such as bindweed, chickweed, and Veronica spp. in cereals. It is a U.S. EPA restricted Use Pesticide (RUP), indicating its importance in maintaining crop health and yield.
Bromoxynil octanoate is also used as a herbicide for various crops, including alfalfa seedlings, barley, corn, flax, garlic, grasses, mint, oats, onions, popcorn, rye, sorghum, triticale, and wheat. Its selective nature allows it to target specific weeds without causing significant harm to the desired crops.
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
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).

Check Digit Verification of cas no
The CAS Registry Mumber 1689-99-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,8 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1689-99:
(6*1)+(5*6)+(4*8)+(3*9)+(2*9)+(1*9)=122
122 % 10 = 2
So 1689-99-2 is a valid CAS Registry Number.
