Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Henry's law constant was calculated based on vapor pressure and water solubility using the EPI Suite (V3.12) computer program. The Henry's law constant was estimated to be 0.0424 atm-m3/mole for the test substance, which indicates that volatilization from water, if it occurs is relatively slow. Hence, the test substance most likely volatilizes slowly to air from aqueous environments and probably has limited volatilization from soil.

 

Conclusions:

Henry's law constant was calculated based on vapor pressure and water solubility using the EPI Suite v4.0 computer program. The Henry's law constant was estimated to be 0.0424 atm-m3/mole for the test substance, which indicates that volatilization from water, if it occurs is relatively slow.

Key value for chemical safety assessment

Henry's law constant (H) (in Pa m³/mol):
4 269.18
at the temperature of:
25 °C
