Product Name:Temephos
English Name:Temephos
CAS No.:3383-96-8
Aliases:Abate, Biothion, Difenfos, O,O,O',O'-tetramethyl O,O'-thiodi-p-phenylene bis(phosphorothioate)
Molecular Formula:C16H20O6P2S3
Physical Properties:Pure product is white crystalline solid; technical grade is light brown viscous oily liquid. Melting point 30–30.5°C, relative density (25°C) approximately 1.32, very low vapor pressure. Almost insoluble in water (~0.03 mg/L), soluble in acetone, ethanol, ether, benzene and other organic solvents. Stable to light, heat and weak alkali; hydrolyzed by strong alkali and acid.
Uses:Temephos is an organophosphorus insecticide used primarily as a larvicide for controlling mosquito larvae, midges and blackflies in drinking water sources, ponds and swamps. It also has contact activity against adult mosquitoes and relatively low mammalian toxicity with short environmental persistence.
Technical Specifications:
Molecular weight: 466.47
Content (technical grade): ≥95%
Melting point: 30–30.5°C
Relative density (25°C): approx. 1.32
Water solubility (20°C): <0.03 mg/L
