Reference
Endpoint:
partition coefficient
Type of information:
(Q)SAR
Adequacy of study:
supporting study
Study period:
2018-02-15
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Data based on calculations using KOWWIN v 1.68 (EPI Suite v4.10).
Principles of method if other than guideline:
KOWWIN v 1.68 (part of EPISuite) was used. The validity and applicability criteria, as described in the REACH guidance R.6, of the QSAR estimation have not been evaluated in detail. However, the QSAR model is a well-known, widely used and commonly accepted tool for deriving log Pow values for chemical structures based on the summation of atom/fragment values.
Type of method:
other: calculated
Partition coefficient type:
octanol-water
Key result
Type:
log Pow
Partition coefficient:
3.939
Remarks on result:
other: CAS 677-69-0
Conclusions:
The log Pow of CAS 677-69-0 was calculated to be 3.94 with KOWWIN v1.68.
