Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 114 g/mol, the experimentally determined vapour pressure of 427.1 kPa (at 20 °C) and the water solubility of 373 mg/L (at 24 °C), the Henry's law constant at environmental temperature (12 °C) is calculated to be 8.7E+04 Pa·m³/mol. Based on this value, the substance is expected to volatilise rapidly from water.
