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 . PubChem is the world’s largest collection of freely accessible chemical information. A quick guide to finding ChemIDplus data on PubChem can be found at Accessing ChemIDplus Content from PubChem . In addition, About PubChem provides a wealth of information ing PubChem, including sections on: PubChem News , which provides updates about PubChem. What’s in PubChem , which explains the different components of PubChem and the content included in the site. PubChem Search and Tools , which includes information on advanced search features and chemical structure searching. Programmatic Access, which provides information on programmatical access of PubChem data, including the REST and SOAP API features. A new self-paced PubChem tutorial ( https://www.nlm.nih.gov/oet/ed/pubchem/tutorial/ ) is also available to guide users through the steps to access chemical property and structure data that hundreds of academic, government, and industrial sources contribute to PubChem. It includes step-by-step directions for how to find chemical information using chemical names, identifiers, molecular formulas, gene symbols, proteins, pathways, taxonomies, and structures. New content will continue to be added to ChemIDplus and the Drug Information Portal until November 1, 2022. Both ChemIDplus and the Drug Information Portal will remain available until they are retired in mid-December 2022. The ChemIDplus data (which includes all of the data in the Drug Information Portal) is also available as a bulk download file through the NLM Data Distribution Program and will continue to be available after both sites are retired. After the ChemIDplus site is retired, NLM staff will perform a final review of the data. The final ChemID dataset will be used to update PubChem and will be posted on the NLM Data Distribution site . Also, the older versions of the ChemID files will be removed from Data Distribution. These updates will happen by February 28, 2023. If you have any questions, please contact the NLM Support Center .
