User contributions will help expand open transformation product libraries, which in turn can help improve screening of environmental contaminants as illustrated by the application in this article. As the use of ShinyTPs expands (already with external users using the application), it is important to avoid curating duplicate information. This increases the importance of utilizing the "PubChem Transformations" tab to see which reactions are already available. Since HSDB was discontinued in 2019, new compounds will not be added to the HSDB dataset and thus the TPs of emerging contaminants are not likely to be present. However, it will also be possible to enhance ShinyTPs to other sections of PubChem (e.g., the "Pharmacodynamics" section) in the future to expand the scope of this effort further. Finally, for current studies describing transformation processes, the inclusion of the results in a standard FAIR reporting template could ease the addition of these TP reactions into public resources .
