Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The HLC of 0.00118 Pa m3/mol at 12 ⁰C is calculated from the vapour pressure (1.38 * 10 -4 Pa) and water solubility (71 mg/L) at 12 deg C
Key value for chemical safety assessment
- Henry's law constant (H) (in Pa m³/mol):
- 0.001
- at the temperature of:
- 12 °C
Additional information
Volatilisation of organic compounds from surface waters is generally estimated by the Henry’s law constant. The Henry’s law constant is calculated with EUSES from the ratio of the vapour pressure (Pa) and water solubility (g/L). The Henry's Law constant at environmental temperature is 0.00118 Pa.m3/mol at 12⁰C based on the vapour pressure of 2.46e-4 Pa at 20⁰C, water solubility of 0.080 mg/L at 20⁰C and molecular weight of 607.07 g/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.
