On this web site, you can:
The Toolbox can help you find adequate analogues to build a chemical category as well as to establish the arguments to build a category rationale (e.g. similarity of mechanisms of action, similarity of structural functional groups etc.). Specific guidance can be found in the Guidance Document for Using the OECD (Q)SAR Application Toolbox to Develop Chemical Categories According to the OECD Guidance on Grouping of Chemicals.
The chemical category concept is used in several existing legislations for different purposes in different countries. It should be noted that each of those legislations have their own reporting requirements and the acceptance for different purposes might differ. Please note that the Toolbox does not overrule any of those purposes and reporting requirements. It should also be noted that the programmes mentioned above have requirements regarding the quality of the experimental data used for read-across and trend analysis and that the experimental results stored in the Toolbox will have to be verified by the user against those requirements. Users are encouraged to consult the guidance documents for the different legislations. Discussions on regulatory acceptance and legislation-specific procedures on this web site are discouraged.
