- (Q)SAR
- Adequacy of study:
- weight of evidence
- Study period:
- 2017
- Reliability:

- Rationale for reliability incl. deficiencies:
- results derived from a valid (Q)SAR model, but not (completely) falling into its applicability domain, with adequate and reliable documentation / justification
- Justification for type of information:
- 1. SOFTWARE: OECD QSAR Toolbox and Toxtree
2. MODEL (incl. version number): Toolbox Version 3.4 and Toxtree 2.6.13
3. SMILES OR OTHER IDENTIFIERS USED AS INPUT FOR THE MODEL: CC1(C)NCCS1
4. SCIENTIFIC VALIDITY OF THE (Q)SAR MODEL
[Explain how the model fulfils the OECD principles for (Q)SAR model validation. Consider attaching the QMRF or providing a link]
- Defined endpoint:
- Unambiguous algorithm:
- Defined domain of applicability:
- Appropriate measures of goodness-of-fit and robustness and predictivity:
- Mechanistic interpretation:
5. APPLICABILITY DOMAIN
[Explain how the substance falls within the applicability domain of the model]
- Descriptor domain:
- Structural and mechanistic domains:
- Similarity with analogues in the training set:
- Other considerations (as appropriate):
6. ADEQUACY OF THE RESULT
[Explain how the prediction fits the purpose of classification and labelling and/or risk assessment]

In chemico test system
- Details on the study design:
- The QSAR Toolbox is a software for grouping chemicals into categories and filling gaps in (eco)toxicity data needed for assessing the hazards of chemical. The model focuses on intrinsic properties of chemicals (mechanism or mode of action, (eco-)toxicological effects). It enables robust hazard assessment through mechanistic comparisons without testing.
Toxtree is able to estimate toxic hazards by applying plugins in a decision tree approach inclusive a profiler for protein binding alerts.

Applicant's summary and conclusion
- Interpretation of results:
- study cannot be used for classification
- Conclusions:
- The substance is in the applicability domain of 3 out of seven profilers in the OECD Toolbox 3.4, i.e.
Protein binding by OASIS v1.3: no alert found
Protein binding by OECD: no alert found

Not possible to classify for DPRA Cystein/Lysine peptide depletion and Keratinocyte gene expression by the OECD Toolbox. - Executive summary:
The structure activity relationship of 2,2 -Dimehtylthiazolidin was investigated by using the OECD Toolbox 3.4 (released 2016). No alert for protein binding was found. It was not possible to classify the substance for DPRA Cystein/Lysine peptide depletion and Keratinocyte gene expression by the OECD Toolbox.
