- HYPOTHESIS FOR THE ANALOGUE APPROACH
The source and target substances are substances are structurally similar and belong to the structural class of aliphatic diesters. Both substances share a carboxylic diester group, the only difference being that one is a methyl ester of succinic acid while the other is an ethyl ester of succinic acid. Both are expected to be metabolised in a similar manner. The common structure does not include any functional group of concern with regard to genotoxic activity and, as a result, they are regarded as sharing a common mechanism of (lack of) action.
ANALOGUE APPROACH JUSTIFICATION
QSAR tools allow an examination of the structure of both the source substance, dimethyl succinate, and the target substance, diethyl succinate. These tools examine structural alerts for potential activity with regard to genotoxic activity and do not flag alerts for either substance. Given the commonality of structure between the source and target substances and the lack of structural alerts within the two, it is reasonable that the experimental data available on the source substance, dimethyl succinate is indicative of the genotoxic properties of diethyl succinate. - Reason / purpose for cross-reference:
- read-across source

Referenceopen allclose all
The substance was tested at the maximum concentration of 5000 μg/plate and at four lower concentrations. No relevant toxicity was observed with any tester strain at any dose-level. No relevant increase in revertant numbers was observed at any concentration tested.
No precipitation of the tested substance was observed at the end of the incubation period at any concentration.
The substance did not induce increases in the number of revertant colonies in the plate incorporation or pre-incubation assay, at any dose-level, in any tester strain, in the absence or presence of S9 metabolism.
Marked increases in revertant numbers were obtained in these tests following treatment with the positive control items, indicating that the assay system was functioning correctly.
Endpoint conclusion

Justification for classification or non-classification
Non-classification is justified on the basis of negative findings / predictions in 3 separate in-vitro tests for gene mutation / mutagenicity.
