Assessment of chemicals

OECD Quantitative Structure-Activity Relationships Project [(Q)SARs]


(Quantitative) Structure-Activity Relationships [(Q)SARs] are methods for estimating properties of a chemical from its molecular structure and have the potential to provide information on hazards of chemicals, while reducing time, monetary cost and animal testing currently needed.

To facilitate practical application of (Q)SAR approaches in regulatory contexts by governments and industry and to improve their regulatory acceptance, the OECD (Q)SAR project has developed various outcomes such as the principles for the validation of (Q)SAR models, guidance documents as well as the QSAR Toolbox.  The OECD (Q)SAR Project is carried out with the financial assistance of the European Union.

The information on the project and its products are available from the following links:
