NORMAN Suspect List Exchange


As part of a series of workshops in September 2014, NORMAN members expressed the need to exchange various lists of substances to improve their suspect screening efforts. An initiative of the 2015 Joint Programme of Activities involved establishing this website 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. The second column 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.

Recommended programme for the interconversion of chemical identifiers:

1, Open Babel at is an open tool – a chemical expert system (cheminformatics) - for the interconversion of chemical identifiers such as SMILES, InChI and InChIKey. It currently supports several chemical formats and offers both command line-batch mode and graphical user interface. For more information please consult

2, For quick individual entry-based conversions from one chemical format to another Chemical Identifier Resolver at is an alternative.

3, Another command line alternative tool which serve interconversion of chemical identifiers is ChemAxon molconvert at

If you have any feedback or a list that you would like included, please contact
