ChemAxon’s extends PubChem database with crowd-sourced chemistry from the Web

news · 4 years ago
ChemAxon announces that the crowd-sourced chemical structures gathered via its public website,, have been deposited to the Pubchem repository, with approximately one third of the submission being novel. The provision also includes links to valuable structure-based data for each of the submitted structures. is a public website which extracts and displays chemical structures from users browsing of web pages and submitting other documents to the site. The service builds a database of all identified structures, which enables structure (and other) searching of gathered content. Since was started in spring 2009 we have gathered ~300,000 unique structures and inline with the aims of the service, to make chemistry more useful, we deposited the collection into PubChem, the world's largest free public chemistry database. From these ~300,000 structures ~100,000 structures were novel. Continued growth and new users are essential to have a crowd-sourced database that is up-to-date and follows current interests. has been growing well in recent months with 15,000 unique visitors/month in December, up 60% in the last 6 months. We will continue to deposit updates to ensure the utility of the service to the community and to include a link back to data pages where various structure-based calculated properties are presented. The deposition is discussed in more detail at the ChemAxon blog; About is a public website created by ChemAxon for adding chemical resolution to web browsing, chemical names and structure files. The service is free and will be useful to anyone wishing to add chemical structures and predicted data to their web browsing experience or extract chemical structures from web pages and other documents.
