| Hazard Information | Back Directory | [Description]
Clofenacet is a plant growth regulator mainly used on cereals. It is highly soluble in water, non-volatile and moderately persistent in soil systems. Based on its physico-chemical properties it is not expected to leach to groundwater. It has a low to moderate toxicity to most biodiversity. Its mammalian toxicity is low. | [Chemical Properties]

Clofencet is a chemical hybridizing agent (CHA) used in wheat breeding. It can induce the physiological male sterility in wheat. | [Definition]
ChEBI: A pyridazinone that is 1-(p-chlorophenyl)pyridazin-4-one which is substituted at positione 5 and 6 by carboxy and ethyl groups, respectively. It is used (particularly as the potassium salt, known as clofencet-potassium) as a chemical hybridisa
ion agent for commercial hybrid seed production. It is not approved for use within the European Union. | [Production Methods]
Clofencet is produced commercially through a specialised synthesis involving a Lewis acid-catalysed reaction. The process begins with the preparation of 4-chlorophenyl hydrazonoacetaldehyde, which is then reacted with ethyl diazoacetate in the presence of a Lewis acid catalyst. This reaction forms the core structure of clofencet. The synthesis is conducted under controlled conditions to ensure selectivity and yield, and the resulting compound is purified and formulated into agricultural products. Pilot-plant studies have optimized this method for scalability and consistency in commercial production. | [Mechanism of action]
Clofencet acts by inducing male sterility through the suppression of pollen development without affecting female fertility. This selective action is crucial for its use in hybrid seed production. | [Pesticide Type]
