Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.8 (Partition Coefficient)
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 117 (Partition Coefficient (n-octanol / water), HPLC Method)
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- HPLC method
- Partition coefficient type:
- octanol-water
- Analytical method:
- high-performance liquid chromatography
- Type:
- log Pow
- Partition coefficient:
- 2.1
- Temp.:
- 40 °C
- Remarks on result:
- other: pH not reported
- Conclusions:
- The partition coefficient (1-octanol / water) of 2 -chloro-5-chloromethylpyridine was determined as logPow = 2.1.
- Executive summary:
The partition coefficient (1-octanol/water) of 2 -chloro-5-chloromethylpyridine (CCMP) was determined according to OECD 117 guideline and EEC-guideline 92/69/EWG A.8, HPLC-method. Therefore, 9
neutral calibration substances were injected into a HPLC-system under the same analytical conditions (column temperature 40°C) as the test item. A calibration curve was created by using the measured retention times and the known log Pow-values of the calibration substances for linear regression.
From the resulted calibration curve and its equation the log Pow of the substance had been interpolated. The partition coefficient (1-octanol / water) of 2 -chloro-5-chloromethylpyridine was determined as logPow = 2.1.

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
