Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 Henry's law constant is calculated using the equation from EUSES. Using a molecular weight of 246 g/mole, and the experimentally determined vapour pressure of 0.06 Pa (at 25 °C) and water solubility of 5.142 mg/L (at 25 °C), the Henry's Law constant at 25°C and at environmental temperature (12°C) is calculated to be 2.868 and 1.374 Pa·m³/mol, respectively. This Henry's Law Constant shows that volatilisation is of minor importance in the environmental behaviour of the substance (see also distribution modelling).
