| Hazard Information | Back Directory | [Description]
Beta-cyfluthrin is a pyrethroid insecticide. It has a low aqueous solubility, semi-volatile and is not expected to leach to groundwater. It is highly toxic to mammals and may be a neurotoxin. It is also highly toxic to fish, aquatic invertebrates, aquatic plants and honeybees but slightly less toxic to birds, algae and earthworms. | [Chemical Properties]

Refer to the productμs Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support. | [Production Methods]
Beta-cyfluthrin is synthesised through a multi-step chemical process starting with p-fluorobenzaldehyde as the key raw material. The production involves sequential reactions including bromination, condensation, etherification, hydrolysis, and esterification. These steps build the complex pyrethroid structure, which includes a dichlorovinyl cyclopropane carboxylic acid moiety and a cyano-substituted phenoxybenzyl ester. The process is designed to yield a mixture of specific diastereomers that contribute to its potent insecticidal activity. | [Mechanism of action]
Non-systemic with contact and stomach action. Sodium channel modulator. | [Pesticide Type]
