I wrote this add-in a few years ago, but changes made to the EPA Web site caused it to break and at the time I didn't think I could fix it...  However, "where there's a will there's a way" and when I noticed that the search page automatically set focus on the input box that holds the query I realized I could use the SendKeys.Send method in C# .Net to fix it. 

So yes, the EPA CompTox Chemistry Dashboard add-in is working again.  It streamlines firing off queries from inside BIOVIA Draw.  

Here's a video of it working:

The EPA developed the CompTox Chemicals Dashboard ("Dashboard") to provide public access to chemistry, toxicity, and exposure data. This information includes chemical structures, experimental and predicted physicochemical and toxicity data, hazard and bioassay data, and additional links to relevant websites and applications. The data and predictive models within the Dashboard support the Agency’s efforts to identify bioactive chemicals for further testing needs, to support an Agency priority to accelerate chemical hazard assessment data acquisition, and translate effects to protect human health and the environment. Iterative review of the data is ongoing and additional data types are introduced with each release. The Dashboard has information for over one million chemical substances and continues to expand in terms of the number of chemicals represented.
