The QSAR Application Toolbox was developed under the aegis of OECD to facilitate the use of the category approach and QSAR methods to fill data gaps in classification and labeling. Use of the Toolbox will save resources, reduce the need for animal testing, and greatly accelerate the hazard assessment process.

The Toolbox provides the ability to:

• Make estimates of the relevant endpoints for single chemicals, linked to the CAS number or the chemical structure. Obtain summary information on the validation processes and results of the model so that the user can decide for which regulatory purpose the estimate can be used.
• Obtain a list of analogues for a chemical, together with their experimental, or estimated environmental, toxic or health effects.
• Obtain estimates for metabolite activation/detoxification information for the chemical.

The Basic Training Course, which requires some knowledge of chemical structure, provides an overview of the Toolbox databases, modeling system, and use of QSAR methods for managing data and modeling, plus a hands-on introduction to filling data gaps for hazard assessment.

The Training Courses are designed for those charged with developing safety assessments for chemical manufacturers and distributors as well as for those charged with evaluating submitted assessments for new chemicals or those already in use in commerce. Those interested in or conducting research on QSAR tools and database development would also find the training useful.
