NORMAN Suspect List Exchange

In September 2014, NORMAN members expressed the need to exchange various lists of substances to improve their suspect screening efforts. This website was established as part of the 2015 Joint Programme of Activities as a central access point for NORMAN members (and others) to find suspect lists relevant for their environmental monitoring question. All suspect lists currently available are compiled in the table below and on the US EPA CompTox Chemistry Dashboard (website, downloads, chemical lists).

The “Link to full list” column below contains an excel or comma-separated file (csv) with all available information, e.g. as provided as supporting information for the publication, while the third column provides a list of the structures as InChIKeys only, which allows suspect searching using MetFrag or other workflows. The fourth column contains references for the data: please cite these references if you use the respective datasets. 

Recent Suspect Exchange and Dashboard presentations/publications include: ICCE Oslo 2017: NORMAN Suspects meet the Dashboard and NORMAN MassBank and Suspect Exchange; SETAC Mixtures Denver: Identifying Complex Mixtures with Cheminformatics and HR-MS; ACS Fall 2017: Markush Enumeration for UVCBs, a viewpoint article and several presentations at 

Coordination: Emma Schymanski, LCSB; Curation/RTI/toxicity: Reza Aalizadeh & Nikolaos Thomaidis, University of Athens; Nikiforos Alygizakis, Environmental Institute; CompTox: Antony Williams, US EPA; IT: Lubos Cirka, Environmental Institute; Webmaster: Natalia Glowacka, Environmental Institute; Contributors: see below.

Interactive merged list of all suspect substances (update in progress)

NEW (Jan 2019): Huge update: many new and updated lists available with >70,000 new chemicals. Stay tuned for an updated SusDat!

DISCLAIMER: NORMAN SusDat is a compilation of information provided by NORMAN network members and it is a “living document” undergoing constant curation and improvement. NORMAN SusDat has merged many chemical lists provided to the NORMAN Suspect Exchange into a common format and includes selected identifiers and predicted values as a service for NORMAN members. We are working with contributors and cheminformatics experts to resolve many issues and update the list accordingly. The original lists on the Suspect Exchange ( should be consulted to verify chemical information if necessary (see Source column). Please report any issues to

There are several options available to interconvert chemical identifiers:

  1. The CompTox Chemistry Dashboard offers batch search capabilities: to convert CAS, Names or InChIKeys into many other forms easily, including various download possibilities with associated data.
  2. Open Babel currently supports several chemical formats to interconvert e.g. SMILES, InChI and InChIKey, with both command line-batch mode and graphical user interface.
  3. The Chemical Identifier Resolver at is an alternative for quick individual entry-based conversions from one chemical format to another, or for web services.
  4. ChemAxon molconvert at is another command line alternative to interconvert chemical identifiers.
  5. There are many functions available in R: contact Emma Schymanski at for more information if interested.
