### Dataset Summary
[PubChem](https://pubchem.ncbi.nlm.nih.gov) is a popular chemical information
resource that serves a wide range of use cases. It 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. PubChem collects information on chemical structures,
identifiers, chemical and physical properties, biological activities, patents,
health, safety, toxicity data, and many others.
