Reference
Endpoint:
partition coefficient
Type of information:
calculation (if not (Q)SAR)
Adequacy of study:
key study
Study period:
2018-01-05
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
accepted calculation method
Reason / purpose for cross-reference:
reference to other study
Reason / purpose for cross-reference:
reference to other study
Qualifier:
no guideline followed
Principles of method if other than guideline:
As suggested in OECD TG 107, the partition coefficient is determined from the individual solubilities in water and n-octanol since earlier investigations showed that neither the shake-flask or HPLC methods were suitable for this substance.
GLP compliance:
not specified
Type of method:
estimation method (solubility ratio)
Partition coefficient type:
octanol-water
Type:
log Pow
Partition coefficient:
> 2.74
Temp.:
20 °C
Remarks on result:
other: pH not reported

The water solubility was estimated to be < 3.65 g/L (preliminary test)

The solubility in n-octanol was determined to be >2.0 kg/L or rather unlimited

Conclusions:
Log Kow > 2.74
Executive summary:

The partition coefficient of the test item was calculated from the individual solubilities in n-octanol and water at 20 °C. The Log Kow >2.74.

Description of key information
