Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
RA_CAS 70024-69-0_comparable to OECD 107_partition coefficient: Pow > 2.95E5; logPow > 5.47
RA_CAS 61789-86-4_comparable to OECD 107_partition coefficient: Pow > 4.43E6; logPow > 6.65
Key value for chemical safety assessment
- Log Kow (Log Pow):
- 8
- at the temperature of:
- 20 °C
Additional information
The key value was determined in an estimation which is comparable to OECD 107 (Fox & White, 2011). Neither the shake-flask nor the HPLC method are applicable for the test substance, based on its chemical structure. The partition coefficient of the undissociated test substance would be expected to be significantly higher than the estimated results of > 6.65. Based on a prediction with KOWWINv1.68 (Sept 2010), the logPow is 26.14 and 27.90 taking into account the different alkylated chain lengths. For purpose of exposure assessment calculations a logKow of 8.0 was taken into consideration, since this value represents the maximum valid logKow value in EUSES or EU-TGD approach.
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.
