PubChem is the world's largest collection of freely accessible chemical information. Search chemicals by name, molecular formula, structure, and other identifiers. Find chemical and physical properties, biological activities, safety and toxicity information, patents, literature citations and more.
PubChem Compound records are derived summaries that give users access to a rich set of related content. Compound records contain unique chemical structures extracted from contributed Substance records through standardization.
PubChem Structure Search allows the PubChem Compound Database to be queried by chemical structure or chemical structure pattern.
PubChem is a database of chemical molecules and their activities against biological assays. The system is maintained by the National Center for Biotechnology Information (NCBI), a component of the National Library of Medicine , which is part of the United States National Institutes of Health (NIH).
The PubChem homepage (https://pubchem.ncbi.nlm.nih.gov) provides a search interface that allow users to perform any term/keyword/identifier search against all three major databases of PubChem 1-3: Compound, Substance, BioAssay (see Section 3 of Module 4 for data organization in PubChem).
PubChem Part 1: Basic Searching. Part 1 of this section will review how to find chemical information in PubChem starting with chemical names or identifiers, molecular formulas, gene symbols, proteins, pathways, taxons, cell lines, and patent numbers. Part 2 will review structure searching.
Find chemical information using chemical names, identifiers, structures, molecular formulas, gene symbols, proteins, pathways, taxons, cell lines, and patent numbers. Identify the academic, governmental, or industrial sources that contribute data to PubChem.
