Description of key information

In accordance with REACH Chapter R.7A Endpoint Specific Guidance, specifically R.7.1.17.1 Information Requirements on Dissociation Constant, if the substance cannot dissociate due to a lack of relevant functional groups, the dissociation constant is irrelevant. The substance does not contain functional groups subject to dissociation, consequently a study is not justified.

Key value for chemical safety assessment

Additional information

The investigation of dissociation constant of the substance is not required because they do not have an ionisable group element.
