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

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.
