Cyhalofop-butyl Chemical Properties,Uses,Production

Precautions for Use

Cyhalofop-butyl does not present any useful pre-emergence activity. It can be applied from germination to the four-leafstage of barnyard grass with granular formulations, and from germination to the six-leaf stage with liquid formulations. lt israinfast within 2-3 hours and has no residual activity. The US product label states that 2.3 L/ha of crop oil concentrateshould be added to the tank for all treatments. The product poses low risk to nearby crops such as cotton, soybeans andvegetables but Dow advises that drift to more sensitive crops such as maize, nectarines, peaches, sugar cane and sorghum should be avoided.

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.Cyhalofop-butyl.jpg

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.
