Partition coefficient
Administrative data
Link to relevant study record(s)
- Endpoint:
- partition coefficient
- Type of information:
- calculation (if not (Q)SAR)
- Remarks:
- Migrated phrase: estimated by calculation
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: data from modelling databases
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- other: estimated data
- Principles of method if other than guideline:
- To determine the octanol- water partition coefficient of the test chemical
- GLP compliance:
- not specified
- Type of method:
- other: estimated data
- Partition coefficient type:
- octanol-water
- Type:
- log Pow
- Partition coefficient:
- -0.91
- Remarks on result:
- other: no additional details available
- Conclusions:
- The estimated logPow of (5or8)-aminonaphthalene-2-sulphonic acid was -0.91
- Executive summary:
The octanol - water partition coefficient of the test chemical was estimated using Danish (Q)SAR Database
The estimated logPow of (5or8)-aminonaphthalene-2-sulphonic acid was -0.91
This value indicates that (5or8)-aminonaphthalene-2-sulphonic acid is hydrophillic in nature.
