Description
Fenpyroximate is a pyrazolium insecticide used to control important phytophagous mites in fruit and other crops. It has a low aqueous solubility and is not considered a volatile substance. Whilst it is not normally persistent in water bodies, it can be persistent in soils depending upon local conditions. Based on its physico-chemical properties fenpyroximate is not expected to leach to groundwater. Toxicity to biodiversity tends to be considered high to moderate. It has moderate oral toxicity to humans and there are concerns that it may be a developmental/reproduction toxin.
ChEBI: Fenpyroximate is a pyrazole acaricide and a tert-butyl ester. It has a role as a mitochondrial NADH:ubiquinone reductase inhibitor. It derives from a hydride of a 1H-pyrazole.

tert-Butyl 4-[[[(E)-[(1,3-Dimethyl-5-phenoxy-1H-pyrazol-4-yl)methylene]amino]oxy]methyl]benzoate Use and Manufacturing
Acaricide.
Fenproxymate is commercially produced through a multi-step synthesis involving pyrazole-based intermediates. A key step includes the preparation of pyrazole-1,3-dimethyl-5-phenoxy-4-carboxaldehyde oxime, which serves as a crucial building block. This intermediate is then reacted with methyl isocyanate or similar carbamoylating agents to form the final carbamate structure of fenproxymate. The reactions are typically carried out in organic solvents under controlled temperature and pH conditions to ensure high yield and purity.
Acaricide, Miticide, Insecticide: Used to control spider mites in greenhouses.
