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.
