A free chemical database maintained by the National Center for Biotechnology Information, providing information on chemical structures, properties, and biological activities.
Portmanteau of 'public' and 'chemistry,' created in the early 2000s as part of the NIH's effort to make chemical information freely accessible to researchers worldwide. Represents the democratization of scientific data.
PubChem exemplifies how the internet revolutionized scientific research by making vast chemical databases freely accessible to anyone with curiosity. Before such databases, finding chemical information required expensive subscriptions and library access, creating barriers that PubChem demolished.
