Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Any other information on results incl. tables

Over time, the substance will preferentially distribute into the compartment sediment (50.1%) and into the compartment soil (49.5%). The substance will be slightly distribute into the compartments biota (0.03%), suspended sediment (0.3%) and air (0.02%). The substance will be ionized at lower environmentally pH, so the distribution into water may be appropriate. The data refer to the uncharged molecule (calculated pKa value: 10.4, SPARC On-Line Calculator)
