Chemistry: Public Access Resources

PubChem is an open chemistry database at the National Institutes of Health (NIH). Since the launch in 2004, 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.

The Cambridge Crystallographic Data Centre (CCDC) are world-leading experts in structural chemistry data, software and knowledge for materials and life sciences research and development.

Helping students make connections between chemistry and the world around them.
