Description of key information

During a preliminary test, the partition coefficient (n-octanol/water) (Pow) was estimated to be < 6x10-5 (log Pow < -4) as a quotient of the maximum solubility of the test item in n-octanol and water.

During a second preliminary test (simplified flask-shaking method), the test substance precipitated at the n-octanol-buffer interface. Because of this 'interface-effect' and because the flask-shaking method is only applicable for pure test substances (which the test item is not) and for -2 < log Pow < 4, the main study was not performed.
