Hosted by the National Library of Medicine, PubChem is a comprehensive, open-access chemical database maintained by the National Center for Biotechnology Information (NCBI) at the National Institutes of Health (NIH). It aggregates data from over 1,000 sources, including government agencies, chemical vendors, and scientific journals, to provide detailed records on more than 119 million unique chemical structures. The platform provides:
- Chemical nomenclature, structural identifiers (SMILES, InChI), and 2D/3D molecular visualizations.
- Physicochemical properties, biological activities, and high-throughput screening bioassay results.
- Safety and toxicity profiles, including Laboratory Chemical Safety Summaries (LCSS) and regulatory data.
- Integrated patent information and consolidated scientific literature citations linked to specific compounds.
The largest (?) online database and most complete information freely available from what we could test.
Pharmaceutical scientists and medicinal chemists utilize PubChem to identify lead compounds and develop predictive models for drug discovery through high-throughput screening data. Chemical engineers and manufacturing professionals leverage the platform’s Laboratory Chemical Safety Summaries to conduct hazard assessments and ensure regulatory compliance during process design.
