PubChem is a database of chemical molecules and their activities against biological assays maintained by the National Center for Biotechnology Information (NCBI), a component of the National Library of Medicine, which is part of the United States National Institutes of Health (NIH).
The system contains three primary databases:
PubChem data is available through a web interface, programmatically via the PUG REST API, and as bulk downloads via FTP. The system supports structure searches, chemical property information, biological activities, safety and toxicity information, patents, literature citations, and links to related resources.
All PubChem data is in the public domain and can be freely downloaded and used for both commercial and non-commercial purposes.
