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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
1.65 (calculated, KOWWIN v1.67a, EPISUITE v4.00)
Key value for chemical safety assessment
- Log Kow (Log Pow):
- 1.65
Additional information
Due to the gaseous nature of the substance having a boiling point in the range of -26.2°C (The Beilstein database. Reference: Miller - 1951 ) to -26.8°C (The Beilstein database. Reference: Henne - 1948) and its partition to the atmosphere, as well as the consequent difficulty to appropriately test CTFE and provide meaningful results, no experimental data are reported in this section. However, in order to evaluate the partition coefficient of CTFE despite the fact that it is expected to rapidly partition to the atmosphere compartment, the result of the KOWWIN model (v.1.67a, EPI Suite v 4.0) is reported.
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.
