On December 12, 2022, PubChem will serve as NLM's single source for chemical information. NLM is retiring ChemIDplus and the Drug Information Portal, two chemical property information sites, to better focus our development efforts on a single, integrated source of chemical information. All of the data found in ChemIDplus and the Drug Information Portal is currently available and will continue to be available in PubChem.
