Detailed Product Description

Chemical name: a racemate comprising (S)-alpha-cyano-3-phenoxybenzyl (1R)-cis-3-

(2,2-dichloro-vinyl)-2,2-dimethylcyclopropane carboxylate and(R)-alpha-cyano-3-phenoxybenzyl (1S)-cis-3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropane carboxylate.

Molecular formula: C₂₂H₁₉Cl₂NO₃

Molecular weight: 416.30

CAS: 67375-30-8

Physical and chemical property: colourless crystals or white powder, Stability:

Highly stable to light and elevated temperatures. It is resistant to acidic hydrolysis but undergoes ester cleavage in environmental (basic) aquatic conditions. It has optimum stability at pH = 4. Its low solubility in water indicates a low bioavailability in aquatic situations.

Melting point: 81.4-84.0°C (pure material) ,Boiling point: 200 °C at 9.31 PA ,Vapour pressure: 3.4 x 10-7 Pascals at 25 °C (pure material) ,Octanol-Water partition coefficient: p = 3.16 x 105 ,Refractive index: 0.19 x C + 1.344 (C = concentration in kg/l up to 0.25, only in acetonitrile) ,True density: 1330 kg/m3 (typical for pure material)

Solubility (g/l at 21°C): in n-Hexane:6.5,  in Propanol-2: 9.6,in Methanol: 21.3,in Ethyl acetate: 584, in Toluene: 596, in Fat: 78, in Water: 2.06 m g/l at 20°C

Toxicity: Harmful if swallowed. May be harmful by inhalation or contact with skin. Irritant to skin, eye and respiratory system. ORL-RAT LD50 400 mg kg-1
