Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Water Sol from Kow (WSKOW v1.42) Results:

See attachment in Attached background material for more details.

Water Sol: 0.6891 mg/L

Description of key information

Mass solubility: 0.0069 g/L (Sparingly Soluble) Unbuffered Water pH 9.02 Temp: 25°C [Calculated using Advanced Chemistry Development (ACD/Labs) Software V11.02 (© 1994-2018 ACD/Labs)]
Water solubility at 25°C: 0.0006891 g/L (WSKOW v1.42 - EPIWEB 4.11)

Key value for chemical safety assessment

Water solubility:
0.689 mg/L

Additional information

Both calculated / estimated values are in the same range (<1 g/L). Intermediate substance is sparingly soluble in water.

Accuracy of WSKOW is considered more documented.
