PubChem Homepage has a new look and feel!

We’ve redesigned PubChem’s homepage to give you easier access to the information you need, where you need it. The mobile-friendly, responsive design works on the device you want to use. And the streamlined, intuitive interface puts the data you need at your fingertips.

Here are some of the changes you can expect to see at the new PubChem homepage:

New PubChem Homepage

The menus at the top of the page and the sidebar have been replaced with a minimal set of important links. These links include “About,” “Blog,” “Submit,” and “Contact.” The “About” link will bring you to the PubChem Docs site, where you can find an exhaustive list of PubChem services and documentation.

In addition, data count and data source statistics have been highlighted. Each also includes a link you can follow to get more information on these statistics.

Finally, we’ve improved PubChem’s search New PubChem Homepagecapabilities. The three search boxes for compounds, substances and bioassays have been replaced with a single search box that covers all search types. Search results from the formerly separate search types (compound, substance, and bioassay) have also been integrated into a single search results display. In addition, search in PubChem now directly supports formula and structure search. We have many more details to share with you about the new PubChem search in a separate blog post, so keep your eyes open for that!

We want to know what you think!

PubChem’s new look and feel is a big step forward for PubChem, and we’re excited to share all of the improvements we’re making across PubChem with you!
