EPA: EPI Suite™ analysis (U.S.)

Modeling (Computer)

Modeling, Toxicology

The US EPA EPI Suite is a quantitative structure‒activity relationships (QSAR) modeling system provided by the US Environmental Protection Agency. It uses knowledge of the chemical’s molecular structure to calculate physicochemical properties and predict environmental fates, for example estimating melting/boiling points and biodegradation half-life. Modeling makes it possible to screen out potentially toxic candidate compounds at early stages in the development process, minimizing expensive experimentation. It can also be used to support the results of tests that have not met good laboratory practice (GLP) requirements. Regulatory authorities recommend running more than one QSAR model for each required endpoint.

About our nonclinical animal research models: We provide the utmost care for our research animals and actively pursue advances in animal welfare. As well as ensuring the highest scientific, ethical and regulatory standards, selection of appropriate animal research models for development research is critical to developing safe and effective treatments, devices and products that protect and save lives. Just as we have ethical committee oversight for human trials, we have ethical committees overseeing all aspects of our global animal care and use programs. All of our core, nonclinical facilities are accredited by AAALAC. Learn more about our commitment to replacing, reusing and refining nonclinical research models.
