Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Administrative data
Link to relevant study record(s)
- Endpoint:
- partition coefficient
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- test procedure in accordance with generally accepted scientific standards and described in sufficient detail
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 107 (Partition Coefficient (n-octanol / water), Shake Flask Method)
- GLP compliance:
- yes
- Type of method:
- flask method
- Partition coefficient type:
- octanol-water
- Analytical method:
- photometric method
- Type:
- log Pow
- Partition coefficient:
- < -4
- Temp.:
- 25 °C
- pH:
- 6
- Details on results:
- The following concentrations were obtained after equilibrium:
c (octanol) < 3.10 ^-8 mol/l. No test compound could be detected in the octanol phase, by backextraction (10:1 octanol:H2O) into water and spectrophotometric measurement in water.
c (water): 2.96.10 ^-4 mol/l
The value of LogPow obtained shows that the expected Pow lies outside the range of flask shaking method and should be estimated by the calculation method. - Conclusions:
- Log Pow < -4 at 25 °C and pH 6.0
- Executive summary:
The partition coefficient was first evaluated by using the shake flask method, according to the OECD Guideline 107.
The value of LogPow obtained shows that the expected Pow lies outside the range of flask shaking method and it was suggested that it should be estimated by the calculation method.
Conclusion
Log Pow < -4 at 25 °C and pH 6.0
