Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

According to Section3, part 2, of the Criteria for Inclusion of Substances on Annex IV of Regulation (EC) № 1907/2006, information on this Annex X endpoint are only required when such studies are available. No such data is available.
The estimated Henrys Law Constant (25 deg C) measured by calculation from EPI SuiteTM v4.0 Programwas not incomplecte.This is Exposure Assessment Tools and Models made from EPA (Environmental Protection Agency).
Inorganic compounds are outside the estimation domain and Estimationwas not valid.
 
For Henry LC Comparison Purposes:
Henrys LC [via VP/WSol estimate using Estimated values]:
HLC:  5.101E-030 atm-m3/mole (5.169E-025 Pa-m3/mole), which is almost zero

Key value for chemical safety assessment

Henry's law constant (H) (in Pa m³/mol):
0
at the temperature of:
25 °C

Additional information

Henry's law constant at 20°C (dimensionless) :2.23 x 10-19 (calculated)
