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. Since the launch in 2004, PubChem has become a key chemical information resource for scientists, students, and the general public. Each month our website and programmatic services provide data to several million users worldwide.

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.

Founded in 1876 and chartered by the U.S. Congress, we are one of the world’s largest scientific organizations with more than 173,000 individuals in our global community across 140 countries. Our mission is to advance the broader chemistry enterprise and its practitioners for the benefit of Earth and all its people. Our vision is to improve all people’s lives through the transforming power of chemistry.

Welcome to the Chemistry library!
Chemistry is the study of matter and the changes it undergoes. Here you can browse chemistry videos, articles, and exercises by topic. We keep the library up-to-date, so you may find new or improved material here over time.
