Key value for chemical safety assessment

Additional information

According to the "Guidance on information requirements and chemical safety assessment, Chapter R.7a: Endpoint specific guidance”, p. 173, the study does not need to be conducted if the substance cannot dissociate due to the lack of relevant functional groups. In this case the dissociation constant is irrelevant. 1,1’-DPE has no functional groups which can dissociate. Therefore testing is not justified.
