Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Partition coefficient
Administrative data
Link to relevant study record(s)
- Endpoint:
- partition coefficient
- Type of information:
- (Q)SAR
- Adequacy of study:
- supporting study
- Reliability:
- 3 (not reliable)
- Rationale for reliability incl. deficiencies:
- results derived from a (Q)SAR model, with limited documentation / justification, but validity of model and reliability of prediction considered adequate based on a generally acknowledged source
- Justification for type of information:
- A QSAR analysis was performed in order to have an idea of the estimate value of log Pow of ammonium sulphamidate.
However, due to the fact that ammonium sulphamidate cannot be studied by QSAR, sulphamidic acid was tested here as a representative compound of ammonium sulphamidate. - Qualifier:
- according to guideline
- Guideline:
- other: REACH Guidance on QSARs R.6 (2008)
- GLP compliance:
- no
- Type of method:
- other: calculation method (KOWWIN v1.68 estimate)
- Partition coefficient type:
- octanol-water
- Key result
- Type:
- log Pow
- Partition coefficient:
- -4.34
- Remarks on result:
- other: pH and temperature not measured as it is a computer prediction
- Conclusions:
- Ammonium sulphamidate cannot be studied by QSAR, therefore sulphamidic acid was tested as a representative compound of ammonium sulphamidate.
Based on a computer prediction (EPIsuite, KOWWIN v1.68 estimate), sulphamidic acid is estimated to have a very log Pow, i.e. -4.34.
