PubChem

Last updated: .

PubChem is an open chemistry database at the National Institutes of Health (NIH). It aims to be the world’s largest collection of freely accessible chemical information.

PubChem facilitates the search of chemicals by name, molecular formula, structure, and other identifiers. It provides information onchemical and physical properties, biological activities, safety and toxicity information, patents, literature citations and more.

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.
