Link to relevant study record(s)
- Endpoint:
- partition coefficient
- Data waiving:
- study technically not feasible
- Justification for data waiving:
- the study does not need to be conducted because the substance decomposes
- Endpoint:
- partition coefficient
- Type of information:
- (Q)SAR
- Adequacy of study:
- key study
- Study period:
- 2018-04-12
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- results derived from a valid (Q)SAR model and falling into its applicability domain, with adequate and reliable documentation / justification
- Justification for type of information:
- The experimental study for log P determination is technically not feasible because the test item is not hydrolytically stable. Therefore, QSAR estimation is used to cover the endpoint. Please refer to QPRF/QMRF documentation for detailed information on model suitability.
- Qualifier:
- according to guideline
- Guideline:
- other: Guidance on information requirements and chemical safety assessment Chapter R.6: QSARs and grouping of chemicals
- Version / remarks:
- May 2008
- Principles of method if other than guideline:
- QSAR prediction using KOWWIN v1.68 of EpiSuite v4.11. QSAR calculation is based on the fragment constant methodology.
- GLP compliance:
- no
- Type of method:
- calculation method (fragments)
- Partition coefficient type:
- octanol-water
- Specific details on test material used for the study:
- SMILES: CC(C)N(C(C)C)P(OCCC#N)N(C(C)C)C(C)C
- Key result
- Type:
- log Pow
- Partition coefficient:
- 4.04
- Temp.:
- 20 °C
- Remarks on result:
- other: pH not available in QSAR prediction.
- Details on results:
- see QPRF/QMRF
- Conclusions:
- The estimated log Pow = 4.04 for the test item is comparably high and suggests hydrophobic properties associated with a great potential for adsorption and bioaccumulation.
- Executive summary:
The estimated log Pow = 4.04 for the test item is comparably high and suggests hydrophobic properties associated with a great potential for adsorption and bioaccumulation. The test item is considered to be in the applicability domain of the model and the result is considered adequate for a regulatory conclusion.

Description of key information
The experimental study for log Pow determination is technically not feasible because the test item is not hydrolytically stable and decomposes rapidly during testing. Therefore, the log Pow is estimated using KOWWIN v4.11 from EpiSuite v1.68. The estimated log Pow = 4.04 for the test item is comparably high and suggests hydrophobic properties associated with a great potential for adsorption and bioaccumulation.
Key value for chemical safety assessment
- Log Kow (Log Pow):
- 4.04
- at the temperature of:
- 20 °C
Additional information
The test item is considered to be in the applicability domain of the model and the result is considered adequate for a regulatory conclusion.
