| Hazard Information | Back Directory | [Chemical Properties]
White crystalline solid or powder. | [Uses]
Herbicide. | [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. | [First aid]
If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
15 minutes, occasionally lifting upper and lower lids. Seek
medical attention immediately. If this chemical contacts the
skin, remove contaminated clothing and wash immediately
with soap and water. Seek medical attention immediately.
If this chemical has been inhaled, remove from exposure,
begin rescue breathing (using universal precautions) if
breathing has stopped, and CPR if heart action has stopped.
Transfer promptly to a medical facility. When this chemical
has been swallowed, get medical attention. Do not induce
vomiting when formulations containing petroleum solvents
are ingested. Otherwise, give large quantities of water and
induce vomiting. Do not make an unconscious person
vomit. | [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. | [Definition]
ChEBI: Fomesafen-sodium is an organic sodium salt that is the sodium salt of fomesafen. A protoporphyrinogen oxidase inhibitor, it was specially developed for post-emergence control of broad-leaf weeds in soya. It has a role as an agrochemical, an EC 1.3.3.4 (protoporphyrinogen oxidase) inhibitor and a herbicide. It contains a fomesafen(1-). | [Production Methods]
Fomesafen-sodium is manufactured by first producing fomesafen, a diphenyl ether herbicide, through a sequence that builds the aryl-ether core and introduces the sulfonamide-phenoxy functionality using robust electrophilic aromatic substitution and coupling chemistry typical of this class. Once the neutral fomesafen acid is obtained and purified, it is converted to its sodium salt via controlled neutralisation with aqueous sodium hydroxide, yielding the technical material. | [Mechanism of action]
Selective, absorbed by leaves and roots. Inhibits protoporphyrinogen oxidase (PROTOX), leading to irreversible cell membrane damage. | [Pesticide Type]
