Version 2.1 of the OECD QSAR Toolbox to group chemical substances into categories is now available to download

Helsinki, 17 February 2011 - The software helps registrants and authorities to use (Q)SARmethodologies to group chemical substances into categories and to fill data gaps by read-across, trend analysis and to assess the (eco)toxicity hazards of a particular chemical without new testing under REACH. This help to save costs and avoid unnecessary animal tests.

The user can:

  • Identify analogues for a chemical, retrieve experimental results available for those analogues and fill data gaps by read-across or trend analysis.
  • Categorise large inventories of chemicals according to mechanisms or modes of action.
  • Fill data gaps for any chemical by using the library of (Q)SAR models.
  • Evaluate the robustness of a potential analogue for read-across.
  • Evaluate the appropriateness of a (Q)SAR model for filling a data gap for a particular target chemical.
  • Build QSAR models.

Version 2.1 has improved profiling and program modules and an installation suite.

The release is part of a four-year collaborative project between the OECD and ECHA.
