- Endpoint:
- partition coefficient
- Type of information:
- read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- key study
- Study period:
- September - November 2020
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Reason / purpose for cross-reference:
- read-across: supporting information
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 117 (Partition Coefficient (n-octanol / water), HPLC Method)
- Deviations:
- no
- Principles of method if other than guideline:
- The test item is not stable and hydrolyses within a few minutes when in contact with water: Therefore, it was decided to measure the partition coefficient of the degradation product itself.
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- HPLC method
- Partition coefficient type:
- octanol-water
- Specific details on test material used for the study:
- - Storage conditions: Keep in a cool dry place. Store under nitrogen at room temperature; keep away from any humidity and sunlight.
- Analytical method:
- high-performance liquid chromatography
- photometric method

- Type:
- log Pow
- Partition coefficient:
- 0.885
- Temp.:
- 25 °C
- pH:
- 7.64
- Conclusions:
- The Log Pow (n-octanol/water) of the test item was determined to be 0.885 at 25 °C.
- Executive summary:
The partition coefficient n-octanol/water (Pow) was measured according to OECD test method no. 117, using the HPLC-method with UV-detection. The substance to be registered is not stable and hydrolyses within a few minutes when in contact with water: Therefore, it was decided to measure the partition coefficient of the degradation product itself. The Log Pow (n-octanol/water) of the degradation product was determined to be 0.885 at 25 °C.
- Endpoint:
- partition coefficient
- Type of information:
- read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- weight of evidence
- Reliability:
- 2 (reliable with restrictions)
- Reason / purpose for cross-reference:
- read-across source
- Reason / purpose for cross-reference:
- read-across source
- Principles of method if other than guideline:
- The substance to be registered is a sparingly soluble substance, which hydrolyses in aqueous solutions immediately (t1/2 < 1 minute) resulting in an organic degradation product (LZ399) and copper. Therefore the Log Pow was determined on the degradation product LZ399. The Log Pow of the Copper Chelate complex cannot be calculated, as the calculation methods such as EPIWIN are not applicable to metal complexes.
- Key result
- Remarks on result:
- not determinable because of methodological limitations
- Conclusions:
- The Log Pow of the Copper Chelate complex cannot be calculated, as the calculation methods such as EPIWIN are not applicable to metal complexes.
- Executive summary:
The substance to be registered is a sparingly soluble substance, which hydrolyses in aqueous solutions immediately (t1/2 < 1 minute) resulting in an organic degradation product (LZ399) and copper. Therefore the Log Pow was determined on the degradation product LZ399.The Log Pow of the Copper Chelate complex cannot be calculated, as the calculation methods such as EPIWIN are not applicable to metal complexes.
- 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

Description of key information
The partition coefficient n-octanol/water (Pow) was measured according to OECD test method no. 117, using the HPLC-method with UV-detection. The substance to be registered is not stable and hydrolyses within a few minutes when in contact with water: Therefore, it was decided to measure the partition coefficient of the degradation product as such. The Log Pow (n-octanol/water) of the degradation product was determined to be 0.885 at 25 °C. The log Pow for the Zinc Chelate Complex cannot be estimated, as the calculation methods such as EPIWIN are not applicable to metal complexes.
Key value for chemical safety assessment
- Log Kow (Log Pow):
- 0.885
- at the temperature of:
- 25 °C
