| Hazard Information | Back Directory | [Description]
Cyhalofop-butyl is a post-emergence, aryloxyphenoxypropionate herbicide, which is used in controlling weeds in rice plantations. Its mode of action involves the inhibition of acetyl-coenzyme A carboxylase (ACCase) biosynthesis.
Cyhalofop-butyl has a low aqueous solubility and is non-volatile. It is non expected to be eprsistent in soil systems but may be persistent in some water systems depending on local conditions. Cyhalofop-butyl is moderately toxic to fish and aquatic plants but has a low toxicity ti aquatic invertebrates, birds and honeybees. It has a low mammalian oral toxicity. | [Uses]
Cyhalofop-butyl may be used as a reference standard in the determination of cyhalofop-butyl in rice samples using liquid chromatography coupled with diode array detector (LC-DAD). | [Definition]
ChEBI: Cyhalofop-butyl is an aromatic ether. | [Production Methods]
Cyhalofop-butyl is commercially produced through a multi-step synthesis process. The key steps involve etherification of 3,4-difluorobenzonitrile with hydroquinone under alkaline conditions to form 4-(4-cyano-2-fluorophenoxy)phenol. This intermediate is then subjected to condensation with propanoic acid derivatives, followed by esterification with butyl bromide to yield cyhalofop-butyl. The process requires precise control of reaction conditions to maximise yield and minimize side reactions, with solvents like dimethyl sulfoxide and strong bases enhancing efficiency. | [Trade name]
