Additional information

The substance cannot dissociate due to a lack of relevant functional groups. Thus it is scientifically not possible to perform the test. In accordance with column 2 (Specific rules for adaptation from column 1) of REGULATION (EC) No 1907/2006 (REACH), Annex IX, 7.16. (Dissociation constant) a study does not need to be conducted if

- the substance is hydrolytically unstable (half-life less than 12 hours) or is readily oxidisable in water, or

- it is scientifically not possible to perform the test for instance if the analytical method is not sensitive enough.
