PubChem is an open chemistry database at the National Institutes of Health (NIH). “Open” means that you can put your scientific data in PubChem and that others may use it. PubChem has become a key chemical information resource for scientists, students, and the general public. PubChem mostly contains small molecules, but also larger molecules such as nucleotides, carbohydrates, lipids, peptides, and chemically-modified macromolecules. We collect information on chemical structures, identifiers, chemical and physical properties, biological activities, patents, health, safety, toxicity data, and many others.

A search engine for scientific data and other information that can be hard to find using more common search engines. Results include diagrams and images that illustrate the data and text.
