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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
5.4.2.001 (HSDB (2005)/Hine and Mookerjee (1975)): 5.9X10-4 atm-cu m/mole at 25 °C (experimental value).
5.4.2.002 (HENRYWIN v3.20):
Bond Estimation Method for LWAPC Value: 55.2 Pa*(m3/mol) at 25 °C
Group Estimation Method for Log Gamma Value: 54.2 Pa*(m3/mol) at 25 °C
Key value for chemical safety assessment
- Henry's law constant (H) (in Pa m³/mol):
- 59.5
- at the temperature of:
- 25 °C
Additional information
The experimental value of 5.9X10 -4 atm-cu m/mole at 25 °C (pointed out as key data) gives after unit conversion an approximate value of 59.5 Pa*(m3/mol). The value estimation by the use of HENRYWIN v3.20 resulted in similar values which were slightly lower: 55.2 Pa*(m3/mol) and 54.2 Pa*(m3/mol).
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.
