EC number: 943-080-0
CAS number: -
The log Koc of the substance should be stated as a range of 3.83-14.1, based on the calculated log Koc values of the individual components.
During pre-tests for the determination of the log POW of
the substance using the HPLC method according to OECD 117 resp. EU A.8
it became obvious that the solubility of the test item was not
sufficient for evaluation using UV or light scattering detection. The
following solubility values were obtained with the tested solvents:
< 1 g/L
< 1 g/L
< 1 g/L
> 2 g/L
After addition of water, at least parts of the dissolved material
precipitated. As the solubility of different components usually
differs,this finding aroused doubts if the dissolved material is
representative for the test item.
As the same restrictions regarding detection and solvent selection
apply for the determination of the adsorption coefficient as for the
n-octanol/water partition coefficient, a calculation of the log KOC based
on the known and expected components of the test item was recommended by
the study director.
Log Koc value for the substance was calculated with a widely used
QSAR model developed by EPA, KOCWIN v. 2.00.
Each individual component of this UVCB substance has been evaluated
The predicted Log Koc is in the range 3.83 - 14.1, based on the
calculated log Koc values of the individual components.
Each component falls within the applicability domain of the model,
thus all predictions can be considered of high reliability. A QMRF for
the model and a QPRF for the prediction are available.
