ChemIDplus Updated

Wednesday, July 23rd, 2014

ChemIDplus, one of the resources available via TOXNET, has a new interface and updated functionality. ChemIDplus is a dictionary of over 400,000 chemicals with links NLM databases and other resources.

In the Advanced Search, a  new “3D” button on search results pages provides calculated three dimensional structure models for over 300,000 chemicals and 645,000 variations.  Users can adjust the rotation speed, the image type (ball and stick, space fill, wireframe), and 3D angle of viewing; dragging the image changes its orientation. Right clicking on the structure box provides other control options such as color, style, measurements, and computation.

To see the changes, visit ChemIDplus, or read more about the changes in the NLM Technical Bulletin.
