Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Due to the complex nature of the substance (having multiple isomeric forms), partitioning behaviour of the substance will be correspondingly complex. No experimental determination giving log Kow value representative of the whole substance is considered possible. Log Kow is therefore estimated by read-across from a close chemical analogue (showing close similarity of chemical structure and solubility plus reactivity in water). This leads to a log Kow value of <0.9 at 20C
Key value for chemical safety assessment
- Log Kow (Log Pow):
- 0.9
- at the temperature of:
- 20 °C
Additional information
QSAR calculation using the KOWWIN programme of the US EPA.calculates log Kow to be a very low value (-8.28): this supports a conclusion of preferential partitioning into water, but is considered to be an unusually low value. The expermentally determined log Kow value of the close chemical analogue is therefore preferred for assessment of the registered substance.
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.
