Fomesafen Usage And Synthesis

Chemical Properties

White crystalline solid or powder.

Uses

Fomesafen is a protoporphyrinogen oxidae (PPO) inhibitor.

Definition

ChEBI: Fomesafen is an N-sulfonylcarboxamide that is N-(methylsulfonyl)benzamide in which the phenyl ring is substituted by a nitro group at position 2 and a 2-chloro-4-(trifluoromethyl)phenoxy group at position 5. A protoporphyrinogen oxidase inhibitor, it was specially developed for use (generally as the corresponding sodium salt, fomesafen-sodium) for post-emergence control of broad-leaf weeds in soya. It has a role as a herbicide, an agrochemical and an EC 1.3.3.4 (protoporphyrinogen oxidase) inhibitor. It is an aromatic ether, a N-sulfonylcarboxamide, a C-nitro compound, an organofluorine compound, a member of monochlorobenzenes and a member of phenols. It is a conjugate acid of a fomesafen(1-).

General Description

White crystalline solid. Used as an herbicide.

Reactivity Profile

Fomesafen is incompatible with acids.

Agricultural Uses

Herbicide: After July 25, 2003, flumesafen was not permitted in many countries to be used as an active ingredient on crops except to control weeds in soybean crops, and white, kidney and snap beans. Not approved for use in EU countries. Registered for use in the U.S.

Trade name

BAS 530 04®; FASTER®; FLEX®; FLEXSTAR; FOMESAFEN® SODIUM; PP 021®; REFLEX®; REFLEX® 2LC Herbicide (sodium salt); TORNADO®[C]; TWISTE®[C]; TYPHOON®

Potential Exposure

Chlorophenoxy herbicide. After July 25, 2003, flumesafen was not permitted in many countries to be used as an active ingredient on crops except to con trol weeds in soybean crops, and white, kidney and snap beans. Limited use allowed in some European countries. Incompatibilities: Slowly hydrolyzes in water, releasing ammonia and forming acetate salts.

Shipping

UN2588 Pesticides, solid, toxic, Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required.

Waste Disposal

Do not discharge into drains or sewers. Dispose of waste material as a hazardous waste in a landfill approved and licensed for the disposal of pesti cides. 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.
