Endpoint:
dissociation constant
Data waiving:
study technically not feasible
Justification for data waiving:
the study does not need to be conducted because the substance has no ionic structure

Description of key information

Data waiver: According the ECHA Guidance Ch. R.7a, 2008 (pg 173), "...if the substance cannot dissociate due to a lack of relevant functional groups, the dissociation constant is irrelevant.."  Therefore, as this substance is not ionizable, determination of the dissociation constant is not relevant.

Key value for chemical safety assessment
