PubChem<\/a>\u00a0<\/span>is an open chemistry database at the\u00a0<\/span>National Institutes of Health (NIH)<\/a>. \u201cOpen\u201d means that you can\u00a0<\/span>put your scientific data in PubChem<\/a>\u00a0<\/span>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\u00a0<\/span>website<\/a>\u00a0<\/span>and\u00a0<\/span>programmatic services<\/a>\u00a0<\/span>provide data to several million users worldwide.<\/p>\n 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.<\/p>\n Where does the data in PubChem come from? PubChem records are contributed by hundreds of\u00a0<\/span>data sources<\/a>. Examples include:\u00a0<\/span>government agencies<\/a>,\u00a0<\/span>chemical vendors<\/a>,\u00a0<\/span>journal publishers<\/a>, and more.<\/p>\n
