OTHER INFORMATION ON IDENTITIES AND PROPERTIES
Appearance: White-to-cream crystalline solid
Odour: Mild chemical
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: 81.5°C (pure material)
Melting range: 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)
Alphacypermethrin was determined to be miscible with acetone and dichloromethane at room temperature
