The ChemoTyper application is a tool that allows for searching, matching, and highlighting chemotypes - chemical substructures or subgraphs with optionally embedded atom, bond, electronic, or molecular properties - in datasets of molecules. Typical applications are as follows.
- Searching for structural alerts for toxicity in chemical structure files
- Filtering of chemical structures according to chemotypes
- Visualization and inspection of chemotypes
- Grouping of chemicals according to chemotypes, and
- Fingerprinting of chemical structure sets against chemotypes
The ChemoTyper application houses the ToxPrint chemotypes library. The ToxPrint chemotypes library is a public set of chemotypes developed by Altamira LLC for the CERES project of the U.S. FDA Center for Food Safety and Applied Nutrition (CFSAN). The ToxPrint chemotypes library contains three basic subsets.
- Generic structural fragments
- Ashby-Tennant genotoxic carcinogen rules (J Ashby, RW Tennant 1988)
- Cancer TTC categories (R Kroes et. al. 2004).
Chemotype Editor is a graphical user interface (GUI) application for creating and editing chemotypes. Please visit the Chemotype Editor repository on GitHub.

The ChemoTyper application was developed by Molecular Networks GmbH, Erlangen, Germany under a contract from the U.S. FDA Center for Food Safety and Applied Nutrition (CFSAN), Office of Food Additive Safety.
The XML-based substructure (or chemotype) definition language CSRML was co-developed in collaboration with Altamira LLC, Columbus, OH, USA.
