Results and discussion
Percent distribution in media
- Air (%):
- 0.05
- Water (%):
- 99.9
Any other information on results incl. tables
Over time, the substance will preferentially distribute into the compartment water (99.9%) and slightly into the compartment air (0.05%).
The substance will be ionized at lower environmentally pH, so the distribution into water may be appropriate.
The data refer to the uncharged molecule (measured pKa value: 9.30, Harlan, 2012, rep. no.: 41202877)
