Searching the ChEBI database using the simple text search

Use the search box on the ChEBI home page to enter simple search terms:

1. Name of molecule e.g. paracetamol
2. ChEBI identifier e.g. CHEBI:16526
3. IUPAC International Chemical Identifier (InChI) e.g. InChI=1S/CO₂/c2-1-3
4. Molecular formula e.g.C₆H₁₂O₆
5. Chemical Abstract Service registry number (CAS-RN) e.g. 124-38-9

Guided example: searching for a simple molecule

Let’s start with a simple molecule search e.g. paracetamol as shown in Figure 5:

Once the search is complete, a results page will be returned showing the ChEBI matches to your query (Figure 6). Search results may be downloaded as TSV, XML or SDF files for import into other applications.
