Chemical structure of Caffeine in 2D

Produced by the National Library of Medicine (NLM) and updated daily, ChemIDplus is a dictionary of over 400,000 chemicals (names, synonyms, and structures). It includes links to NLM and other databases and resources, including ones to over 100 federal, state and international agencies.  ChemIDplus Lite is designed for simple searching on name or registry number. ChemIDplus Advanced helps users draw their own structures and perform similarity and substructure searches.  NLM has added some exciting new features to ChemIDplus.

  • 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.  The open source JSMol program is used for viewing these models.  Another feature offers 3D when viewed with Red/Cyan, Red/Green or Red/Blue glasses, allowing for unique visualization of a molecule with depth perception.
  • The ChemIDplus structure box now uses quick-loading Marvin for JavaScript (free; requires IE9 or above). The Marvin Applet version is also available in a pull-down for legacy browsers. (Marvin is loaded on SUL's cluster computers.)
  • ChemIDplus is now IPhone IOS and Android OS friendly. Buttons collapse to neatly fit the phone screen, and the structures can be displayed.
